This PR adds support for a new firmware revision (and hardware revision: missing button below back/forward buttons, various cosmetic changes) of the M705. This version has the model number M-R0073, while the old one has model number M-R0009. The new version uses HID++ 4.5, and has a different wpid, requiring a new descriptor.
I have appended the model number in parentheses after each of the device names, in order to distinguish them. Let me know if you want to label them differently.
Fixes #449 (closed).
