Cleanup WS2811 code and sanitize API.

Browse source 
Removed many magic numbers.
Deduplicated code.
Removed unnecessary local variable usage.

The LED Strip is initialised to WHITE briefly on power up so that it's
possible to visually check that all LEDs are functioning correctly -
white uses each individual RGB diode and draws maximum power.

Introduced an API to allow any code to change any or all LED colors
individually.  This takes a little ram since an additional buffer is
needed - 3 bytes per LED, in addition to the DMA buffer.
