Teensy 3.2 support? #30

Currently Teensy 3.2 board looks like not supported. I've tried to compile the library with PlatformIO (platform = teensy, framework = arduino, board = teensy31) with these errors in result:

lib/FAB_LED/src/FAB_LED.h:684:1: error: prototype for 'void avrBitbangLedStrip<high1, low1, high0, low0, minMsRefresh, dataPortId, dataPortPin, clockPortId, clockPortPin, colors, protocol>::debug()' does not match any in class 'avrBitbangLedStrip<high1, low1, high0, low0, minMsRefresh, dataPortId, dataPortPin, clockPortId, clockPortPin, colors, protocol>'
avrBitbangLedStrip<FAB_TVAR>::debug(void)

Is there any plan to add support for Teensy 3.2? Or do you have any ideas to quick-fix these errors (sorry, I'm not familiar with low-level programming so much)?

I do not have immediate plans to support non AVR controllers, in part because GCC doesn't provide a nop loop primitive for ARM I think, so I'd have to write a small ASM loop for it. Not hard but would require some free time for me to do so.
