Add macros for `rand` traits and tuple converison

Ogeon commented 10 months ago

This should cover most of the remaining repetitive parts that aren't too specific for macros. I may also do a separate refactor pass to make the color source files follow the same structure.

The only observable change should be that Okhsv doesn't require any additional traits for converting from a tuple, compared to other radial types.
