GeoTIFF: Support reading and rendering stripped images

[kylebarron]

This is probably a good chunk of work. We'll need to

• create a separate tileset descriptor for the RasterTileLayer to localize strips instead of tiles
• Support fetching strips instead of tiles
• Check against max GPU texture sizes

---

Should mirror developmentseed/async-geotiff#106

We don't support strip-oriented TIFFs, but some "COGs" are so small that they only have a single tile and don't encode tile_height and tile_width values in the IFD.

For example from source-cooperative/cog-viewer#5
