v0.4.2 - `nusb` support

What's Changed

• nusb support by @jamesmunns in #8

Full Changelog: v0.4.0...v0.4.2

NOTE

Note: v0.4.1 was skipped, because I messed up and did an update without pulling first, which means the #8 merge commit
wasn't present. I've yanked that release, though it is still tagged, and is identical to v0.4.0 other than the version number.
