Switch to FastAPI about localtileserver

[vincentsarago]

@meteoDaniel Titiler uses rio-tiler/rasterio for data access while localtileserver uses the large-image module.

Exactly correct, @vincentsarago! Thanks for chiming in!

localtileserver is honestly a hobby/toy project of mine, and I never thought it would get as many users as it has. I'm hoping to refactor this entirely to only support Jupyter and CLI usage which would drop support for using localtileserver as microservivce in favor of titiler.

Then I also want to experiment with using rio-tiler as the backend for this... but maybe it makes more sense for me to just contribute to rio-viz

It seems there's at least one stakeholder project using the flask app: https://github.com/supervisionearth/svs-tileserver

But they seem to be using a fork so I may go ahead and do this change when I have free time

Dear @banesullivan where is the difference between localtileserver and https://developmentseed.org/titiler/ ? They are using FastAPI as backend.
