Logging USB Feature Reports

[WinkelCode]

Description

This is related to issue #58

I think it could be useful if Nudelta saved a log of the raw content (i.e. what HIDAPI was called with) of all feature reports sent to the keyboard, this would help immensely to understand when a brick happened and what data was malformed. They also shouldn’t be too big, so I think it’s safe to just save them by default.

good idea, will try to do that next version
