Left and right coloring for custom overlay

[SLMapper]

Use case
Coloring the left and right side of a street instead of it's center
E.g. for a custom bicycle overlay

Why
Coloring custom overlay based on tags is nice, but creates too many colors when left, right and both is included in the keys.

Proposed Solution
When coloring key matches a key containing :left, :right or :both, colors the left, right or both side(s) of the street instead (like the bicycle or sidewalk quest)

This was a lot easier to implement than I had thought.

Wow, this is amazing 🚀
Is there a way to test out a pre-release / custom build or should I just wait for the next release?

Could you also support forward/backward?

@tiptoptom this is a different feature, open a new feature request for it. Adding a comment to a closed issue after nearly two years does not bring it to on the agenda and pollutes search and history.

Beside that, do you have an suggestion where/how it should be displayed?
