Replace HSL with OkLCh (#182)

Switch from HSL to OkLCh color. OkLCh color has much better properties for design, so it completely
replaces the uses we had for HSL.  Colors can still be created from HSL, but the internal representation
is RGB or OkLCh.

- Correct names of a few colors. E.g. hotpink -> hotPink
- Simplify API for creating colors
- Update code and docs as necessary
- Dependency updates
- Add Tailwind color palette
- Add Crayola color palette
