construct and use map tile grids
Morecantile is like geo/mercantile (the best tool to work with Web
Mercator tile indexes), but with support for other TileMatrixSet grids.

Morecantile follows the OGC Two Dimensional Tile Matrix Set
specification 2.0 found in https://docs.ogc.org/is/17-083r4/17-083r4.html
