Adds support for Teensy 4.x, as TimerThree doesn't work the same on Teensy4.x as it did on Teensy 3.x.
Also migrates library development in the PlatformIO environment. This is only relevant to development on this library itself, and has no impact on using this library with Arduino.
Finally, cleaned up the code in various places, mostly to address compiler warnings.
