* Allow passing a file with a list of input files to tile-join in response to Issue 69 (https://github.com/felt/tippecanoe/issues/69)
* Do not print usage if -r is specified without a commandline readfrom file
* Add test for -r option to tile-join
* Remove the concept of "separate metadata"
This was an extra level of attribute indirection (features point
to metadata records which point to key and value strings) which was
intended to reduce the size of temporary storage for features with
large numbers of attributes that were also spread across large numbers
of tiles at maxzoom.
For other kinds of features, the extra indirection slowed things down
instead, and, especially when maxzoom guessing was being used, many more
features were having their metadata externalized than could actually
benefit from it.
* Shave a few bytes off temporary files by using more unsigned integers
* Flush stderr after logging progress
* Revert "Shave a few bytes off temporary files by using more unsigned integers"
This reverts commit eef29084ec.
* Limit the size of the string pools and trees to fit in memory
* Add missing #include
* Move the string pool and search tree from mmap to allocated memory
* Sort in allocated rather than mapped memory too
* Also use pread instead of mapping to read in the data to sort
* When the pool gets too big, switch to just the file, not memory
* Switch string pool from memory to disk when memory is 10% full
* Add to-memory versions of the serialization functions
* Crashy work in progress toward compression
* Fix the pointer bug that was causing the crash
* Serialize features into memory rather than straight to disk
* Compress individual features in the temporary files
* Don't need to store the length of the geometry
* Remove per-feature compression; move minzoom back into the object
* Start adding a stream compressor object
* Track file position within fwrite_check()
* Add compressed stream writer functions
* Pull the writing of the serialized feature out to the callers
* Starting toward compression again from a different point
* Hook up more compression functions
* Remove unused code from the other day
* Make enough deflate calls to flush out all the buffered data
* Start on decompression
* Tile number is uncompressed, tile content is compressed
* Work on alternating compressed and uncompressed in decompression
* Closer, but still doesn't work
* Sort of works
* Works until we get to concatenated tiles
* More attempts that don't work
* One bug down
* It made a tileset!
* Handle nonzero initial zooms
* Fix seeking within compressed feature streams
* Tests pass!
* Remove debug spew
* Oops: remember to delete the temporary files so they don't hang around
* Test that fails with the current compression code
* Properly account for bytes read while closing the compressed stream
* Limit the number of warnings about bad label points
* A little more armor when closing decompression
* This time for sure
* A different, less fragile, test that failed previously with compression
* Move feature stream compression to its own file
* Remove now-unused code to deserialize from a file
* Forgot to add the new files
* Remove a little debugging logging
* Add a couple of comments on what it means to be within decompression
* Fix indentation
* Update changelog. Remove stray debugging comment.
* 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.

This moves filtering from the serialization stage to the
tiling stage so that the zoom level can be known to the filter.
The side effect is to carry null attributes much further through
the pipeline than previously.
