Title: PID fixing

Provides a generic PID module, which can be run with software PID calculation or DSP-core acceleration.
Renames pid-hw to pid_hw for consistency with other modules.
NOTE: PID_HARDWARE is defined within pid.h itself, although a test-and-fallback block exists, too. This should probably be moved to a project-level define.

Changes to dfilter_avg module should have already been merged and can be ignored.
