Scott Shawcroft 5b3a143ffe atmel-samd: Rework tick timer to use TC5 and support neopixel status LED. 
The tick timer needed to be reworked because the ASF delay functions also
use the SysTick timer. Now, it uses TC5 and calls out to the autoreset
logic every tick. Fixes #43.

Added neopixel status colors and corrected the latch time from ms to us.
Fixes #42.
