Add rio-pmtiles command line tool. [#338] This is derived from the original mapbox/rio-mbtiles implementation, with changes: * output PMTiles only instead of MBTiles. * Python 3.7+ only. * remove --implementation, --image-dump, --append/--overwrite, --covers features. * bump dependency versions. * better progress reporting; add pyroaring. * update README and license texts. * rio-pmtiles v0.0.6 on PyPI
