Logitech G105 Macro Keys on Linux

Through experimentation, and browsing the code of sidewinderd, I come to a conclustion as to how the keyboard communicates to the system.

Put simply, the keyboard uses HID Feature Reports, which we can manipulate with ioctl in c, or the python module hidapi.

Attached is example code, but this serves as documentation on the values of feature reports.

I will probably make a repo for this one day, but for now this will do.

What this does:

Queries emkc.org for contest info
Queries piston with your code and args, exactly as it would be when being tested by EMKC.
Compares actual output against real, indicating failed and passed tests.

Complain about code quality in comments.
