Slippy map writing support. #572

Closed metasim closed 2 years ago

metasim commented 2 years ago

Requires #571

Adds ability to write out a RasterFrame as a slippy map for visualization. Provides color compositing and rendering options for tweaking results.

I suspect the build is failing on the "in the wild" use case because of AWS permissions. Runs fine locally.
