These packages are obsoleted by the promises API to the built-in Node fs
module. The fs-extra package is also causing problems with broken APIs
that don't behave the same as Node's fs module, and throwing errors
without code properties on them.
A lot of code is repeated in various different ways in order to handle
streaming content to files without overwriting them, whether it's from
web resources or local streams.
Refactor the handling of these streams to all use the same utility
function for creating a write stream, and for the places downloading
urls use the same downloadFile function.
