findVersion takes headless as a plain optional argument, the helper is
checkInstallType, the warning is checkMissingBuiltinIcons and the full
install lookup is inlined into exportData.

Per review, drop host.factorio_graphics_directory. findVersion takes a
headless option that filters installs by build, telling them apart by
data/base/graphics/icons. When the instance runs the headless build the
export looks for a full install of the same major.minor version in the
host's factorio directory. Server startup is unchanged.
If none is found the export still runs, and the reason is included in
the missing icons warning.

If host.factorio_graphics_directory had no install matching the major and
minor version of the instance, or did not exist, findVersion threw and the
whole export failed. Without the setting the same instance exports everything
except the base game icons, so it now logs a warning that names the setting
and exports without it.
An icon that could not be read or decoded, such as a truncated PNG, a
JPEG or a layered icon with no layers, threw out of exportIcons and
failed the whole data export. Log a warning naming the prototype and
export it without an icon instead. Also warn when a mod's zip is
missing while exporting the locale, which was skipped silently.
The headless build has no graphics, so export-data found none of the
base game's icon files. Plain icons were skipped silently and layered
icons were drawn blank and counted as exported.
Skip a layered icon when any of its layers is missing, and log one
warning with the number of base game icon files that were not found.
Add host.factorio_graphics_directory to read builtin mod graphics from
a full install when the instance runs the headless build.
Fixes#1068

FactorioServer.fromOptions finds the Factorio install and generates the
RCON password before constructing, so _version and _dataDir are never
null and setTargetVersion and init are gone. checkForUpdates is now a
module function called before fromOptions.
Instance.fromConfig resolves the version, downloads Factorio if needed
and builds the server, then constructs the instance with it. It runs
before the instance is connected, so the starting and stopped statuses
and the version requests go through the host link. FactorioVersionsRequest
and LatestReleasesRequest now accept host as a source, and the host
tracks starting instances so a second start during a download is
rejected. Plugin loading stays a separate loadPlugins step after the
instance is connected.

* Replace jszip with yauzl and yazl
jszip loads a whole archive into memory to read it and buffers the
output when writing. Saves and mods can be several hundred megabytes,
so read zips with yauzl, which only reads the central directory and
streams entries on demand, and write them with yazl, which streams the
output.
lib gains a ZipArchive wrapper around yauzl with the lookup helpers the
callers need, findRoot() now takes it instead of a JSZip. Saves are
patched by streaming every kept entry into a new zip, mod info.json is
read straight from the file, exports are streamed to the controller and
Factorio zip downloads go through a temp file instead of a buffer.
Patching now inflates and deflates each entry again where jszip reused
the compressed data, on a 336 MB synthetic save that is 7 s instead of
0.7 s, with peak memory going from 416 MB to 151 MB.
Closes#1002

* Copy save entries without recompressing them
yazl inflates and deflates every entry it is given, so patching a save
took ten times longer than with jszip, which reused the compressed
data. Add a ZipWriter to lib that streams entries out as they are
added and copies entries from a ZipArchive byte for byte, with ZIP64
structures when sizes or offsets need them, and use it in patch().
On a 336 MB synthetic save patching now takes 0.4 s at 143 MB peak RSS
against 0.75 s at 417 MB with jszip. Factorio loads the result.

* Handle save write errors before the patch loop awaits them
A write error on the temporary save, such as a full disk, rejected the
pipeline promise while addEntry() or addBuffer() was still pending. Nothing
was listening yet, so the host's unhandledRejection handler exited the
process instead of failing the instance start.

* Keep the export zip cache local to each export
The cache was module level, so when two instances on one host exported at
once, the first to finish closed archives the other was still reading.

* Start writing zips before adding files from disk
yazl reads files passed to addFile() as soon as they are added. An
unreadable file emitted an error while the directory traversal was still
running, before the output pipeline existed, and the process exited on the
uncaught error. build_mod and zipDirectory now start the pipeline first and
reject instead. build_mod also removes the partial zip on failure.

Covers the icon_size default of 64 in the export icon loaders and the
host recreating saves and script-output when an instance is assigned.
Both tests fail when the original fix is reverted.

Migrate the usage of CommonJS specific code and imports to ESM. Roughly
summarised this:
- Changes all require() calls to import statement or expressions.
- Changes usage of module.exports to export statements.
- Replaces require.resolve with import.meta.resolve.
- Replaces conditional imports with conditional subpath imports.
- Replaces module === require.main with import.meta.main.
- Adds the full filename with extention to all relative imports.
- Changes all usage of __dirname and __filename to their import.meta
equivalents.
- Sets "type": "module" in package.json files.
- Removes usage of "use strict".
- Adds .ts an an alias of .js for the webpack build.
Due to differences in how require and import resolves files the plugin
entrypoints will have to include the filename and extension after this
migration in order to work.
Use a separate folder for the TypeScript build for Node.js in the dist
folder. This makes each type of build consistently have its own output
folder instead of being interleaved with the Node.js build.
