Only supports EPSG:3857 WebMercator tiff files

[morandd]

Currently this project has only been tested with EPSG:3857 Web Mercator tiff files. TIFF files in other projections probably won't worry correctly.

MapLibre does support dynamic warping so it should be possible to do reprojection at the browser, but this is an open task.
