Add hardware probe and single-pixel test commands

Browse Source 
- probe: toggles LD/CLK, reads DI state at each step, tests single pixel
- pixel0/pixel1: single pixel at max brightness for testing
- Increased LD pulse timing to 20us
- Increased CLK timing to 2us
- NeoPixel brightness raised to 80
