0.22.4: Re-apply AOI clipping to latest release

[DanSchoppe]

🚨 Reminder: this is a public repo 🚨

This PR rebases the changes from #3 onto the latest 0.22.4 release of TiTiler and a bleeding-edge build of GDAL. This work is being done in tandem with SenteraLLC/rio-tiler#5 to modernize the SenteraLLC fork of TiTiler.

Specifically, it:

• relies on SenteraLLC/rio-tiler rather than cogeotiff/rio-tiler
• supports an aoi argument to the TilerFactory::tile() method such that API consumers can specify base64-encoded GeoJSON to use as a tile clipping geometry. This is passed to the SenteraLLC/rio-tiler::Reader::tile() method described in 7.8.1: Re-introduce aoi argument to Reader::tile() to support clipped tiles rio-tiler#5.
• refactors the deployment/aws/lambda/Dockerfile to:
  • build GDAL (as well as PROJ + GEOS, out of necessity) from source
  • build rasterio from source to make use of the custom GDAL build
  • build TiTiler from source in order to make use of SenteraLLC/rio-tiler
• fixes logging for AWS Lambda
