* PMW33XX drivers overhaul
This combines the PMW3389 and PM3360 drivers as they only differ in the
firmware blobs and CPI get and set functions. The following changes have
been made:
* PMW3389 now gets the same multi-sensor feature that is already available on the
PMW3360.
* Introduced a shared pmw33xx_report_t struct is now directly readable via SPI
transactions instead of individual byte-sized reads, saving multiple
copies and bitshift operations.
* pmw33(89/60)_get_report functions had unreachable branches in their motion
detection logic these have been simplied as much as possible.
* The fast firmware upload option has been removed as this becomes obsolete by
the newly introduced polled waiting functions for ChibiOS polled waiting
* PMW33(60/89)_SPI_LSBFIRST and PMW33(60/89)_SPI_MODE config options
have been removed as they don't need to be configurable.
* All PMW3389 and PMW3360 defines have been unified to a PMW33XX prefix
to reduce code duplication and make the defines interchangeable
* Adjust keyboards to PMW33XX naming scheme
* Install dependencies before executing unit tests.
* Split out UTF-8 decoder.
* Fixup python formatting rules.
