Erica Fischer afc7ca01a2 Calculate an antimeridian-adjusted bounding box in tileset metadata (#82)
* Calculate a new antimeridian-adjusted bounding box

* Add antimeridian bounding box to pmtiles, dirtiles, and tile-join

* Don't take out-of-bounds latitudes into account in the adjusted bbox

* Update changelog

* Forgot to adjust tests after the last change

Erica Fischer c58a8e3b97 Round coordinates instead of truncating them (#60)
* Round coordinates instead of truncating them

* Update all the tests for coordinate rounding changes

* Curses, integer division still truncates

* Fix tests

* Also round instead of shifting when looking for no-op linetos

* Should I worry that the same change for moveto doesn't change any tests?

* Also round instead of shifting when scaling down to maxzoom resolution

* Replace another explicit shift, for origin point

* Round instead of shift when writing clipped geometries to the next zoom

* Fix low-zoom gridding and smaller-than-a-pixel checks

* Don't guess an excessively large maxzoom when there is only one feature

* Add a test for guessing the maxzoom of a single point

* Explicitly sort by index if no other order distinguishes features

* Another affected test

Erica FischerandBrandon Liu 3b2599f587 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.

Eric Fischer 27154c8f06 Cluster onto the previous feature instead of onto the next
This also allows doing the attribute and tilestats all at once
at the end of the tile instead of having to update a feature
to handle the last cluster.
