Point release primarily to address possible 2.8.0 fallout, and possibly some tickets in general and/or 2.7.5 planned remainders (unfinished goals can go to 2.8.2+):

• (expected) clean-up of libusb API variants support [#300 and follow-ups]
• (expected) CI automation for coding style (clang-format)
• (expected) CI automation for use of data points in drivers that conform to patterns defined in docs/nut-names.txt
• (expected) Porting of performance and bug fixes from 42ITy project
• (expected) Bug fixes for fallout possible due to "fightwarn" effort in 2.7.5/2.8.0
