* 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
* 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.

The first feature in a tile can never be dropped, since there is
no previous feature to attach its properties to.
Remove the previous special case that reset the dropping counter
at the first feature within each tile proper (as opposed to the
first feature in each tile, including its buffer, which is now
the one that is guaranteed to be preserved).
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.
The problem was in the case where the CSV provided a new value for
an attribute that replaced an existing value. Both the old and new
value were being included in the tilestats instead of just the new.
