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 the defines.prototypes data structure from the game to find which
prototype sub-types belong in the same base type, and export icons based
on these base type.
This renames the planets category to space-location, signal to
virtual-signal and plits item up into item and fluid. And changes the
exported metadata to include prototypes with no icons, as future code
might want to use it to for example enumerate all item prototypes.
