* add pmtiles.hpp from github.com/protomaps/PMTiles [#10] * tippecanoe main writes pmtiles output. [#10] * detect output format using suffix * after mbtiles is done writing, replace with pmtiles based on map/image tables. * add method to write_json for writing json sub-object. * tippecanoe-decode reads pmtiles input. [#10] * tile-join reads and writes pmtiles. [#10] * pmtiles test suite for decode and tile-join [#10] * add base GitHub CI action for compiling and test suite. * update pmtiles.hpp with z>15 fix * Fix some ordering problems with pmtiles decode * Pmtiles should also pass the raw tiles tests * Eradicate spaces from tileset metadata JSON fields * Eradicate spaces from more test fixtures * Update more tests * Pmtiles tests pass now too * Remove unnecessary sort (and make indent) * Update changelog * The allow-existing test for pmtiles needs -o, not -e * Declare --allow-existing to be unsupported for pmtiles. It was always a bad idea even for mbtiles. Co-authored-by: Brandon Liu <bdon@bdon.org>
