bug-fix: download files across devices now works

[itsthatguy]

fs.rename does not work across devices.

• Implementing mv to replace fs.rename.

[jprichardson]

A few things:

1. Please change the require alignment back to the way it was.
2. Please remove the version bump.
3. Please remove the mv dependency and use fs.move from fs-extra. (fs.move is mv)

That should do it. Thanks.
