RYB/RGB color conversion functions for Lua. Inspired by question on math.stackexchange.

Converts RYB to RGB color scheme, returns triplet. Optional convertTable can be passed, by default uses ryb.IRISSON_RYB_TO_RGB table, alternatively ryb.GOSSET_RYB_TO_RGB can be used. All colors are assumed to be normalized to 1.
