Update Python API to control up to 256 LED

[areid-van]

Exposes two new features in the firmware:

1. Can send data to up to 128 LED (384 bytes) using report 10
2. Can use the 12 bit color mode to double the number of LED that can be controlled for report types 6-10.

Using both features together you can control up to 256 LED. 12 bits still gives a pretty nice range of colors.

Sorry there are a bunch of trivial changes included to work with a different version of the USB library on my system. Those might need to be reverted.
