[Maps] Organize layers into subfolders

[thomasneirynck]

Organizes all layer implementations into their own folders.

For clarity, this renames the existing layers folder to classes.

Reviewed the code, a few SCSS files moved around. LGTM! 🎉

Lots of import reach very deep into folders. What do you think about exporting everything from layers/index.ts so that imports do not need to go so deep into the layers folder?

agreed that this should be made more convenient for client-devs. I'd suggest doing this in another PR, e.g. when working on public API extension points for layers and sources. Right now, this is all internal code, and would just introduce more files and indirection.
