[Feature request] Custom Color Schemes

[trexrush]

Goal

Id like to be able to add a custom color scheme to a visualization (for example, Black instead of Grey on Megaminx)

Possible solution

Im imagining an optional parameter to TwistyPlayer where you can define a color schema

Alternatives

I'm gonna deduplicate this into #157. It's something I want to do eventually, but it's one of those things that sounds deceptively simple but super hard to design correctly.
