Add support for pmtiles output format (#55)

* 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.
