Erica Fischer 794ae2b1eb Tippecanoe-decode and tippecanoe-overzoom changes to improve binning performance (#292)
* Add a tippecanoe-decode option to restrict which attributes to decode

* Plumb buffer and feature limit around

* Check the feature limit

* Clarifying cases where output detail can be unspecified

* Clip bins to the tile buffer instead of just passing them through

* Add missing include

* Missed some tests

* Add --no-tile-compression option to tippecanoe-overzoom

* Update version and changelog

Erica Fischer 66e5d66300 Another round of binning fixes (#274)
* Bin more aggressively if a point doesn't meet the pnpoly test

* Don't clip the points if we are binning

* Fix output of features added to the bin after its closure

* Update tests

* Update version and changelog

Erica Fischer c5f2f0da34 More work on plumbing attribute accumulation through (#263)
* Plumb bounding boxes through potential intersections

* Quick bbox reject for bins that can't possibly intersect

* Inching toward attribute accumulation in megatile handling

* Some sort of test for how all these things interact with each other.

Automatic numeric attribute accumulation does *not* apply to attributes
that have an explicit attribute accumulator set, because the order of
operations is too messy and weird

* More sketching

* More sketching

* Actually do some accumulation

* Put all that behind an --accumulate-numeric flag

* Use the same attribute accumulation logic in binning as in megatiles

* Fix backwards conditional

* Add means, but somehow I have some counts of 0

* Handle aggregated attributes with no base attribute in the feature

* Checkpoint before I break everything

* Found a flaw, now to debug

* Fix a typo that broke accumulation

* Add binning tests

* Make sure IDs make it through on the bins

* Fix count/mean accumulation

* Make the numeric accumulation prefix configurable

* Make sure the accumulate test still works with a different prefix

* Forgot to update this test

* More testing to make sure cluster sizes make it all the way through

* Fix neglected --accumulate-attribute when binning

* Mark unexercised attribute accumulation cases as "can't happen"

* Factor out numeric preservation

* Attrs with the accumulation prefix are just preserved, not accumulated

* Test behavior of prefixed attributes

* Plumbing for exclude and exclude-prefix

* Implement and test attribute prefix stripping in overzoom

* Update version and changelog

* For debugging, make an attribute list of source feature IDs

* Revert "For debugging, make an attribute list of source feature IDs"

Erica Fischer 84f6e887a7 Another try at fixing longitude wraparound for bins (#261)
* Another try at fixing longitude wraparound for bins

* Gonna get it right this time

* Forgot to update the comment

* The filter case was not supposed to reinterpret geometry

* Copy antimeridian-crossing geometries to the other side too

* Getting closer to getting antimeridian-crossing polygons right

* Update changelog and version

Erica Fischer 5b18eea673 Work in progress on binning features in overzoom (#258)
* Factoring out tilestats management from GeoJSON file reading

* Move code around so overzoom can link against parse_layers

* Read the file of bins

* Plumb the bins through to overzoom()

* Some zip code bins to test with

* (Currently non-functional) test of binning

* Starting to spell out the bin matching loop

* Can't flatten points, so don't flatten bins either

* More fleshing out bin traversal

* Bounding box of tile-relative mvt geometry

* Smallest enclosing tile from bbox

* Most of the bin scan

* Add point in polygon check. It crashes.

* Find the matching bins

* GDAL-style bounding boxes have eaten my brain

* Make some features to bin into

* Increment a count as features are found to be within the bins

* Fix longitude wraparound in overzoom bins

* Fix the tests

* Push off attribute copying until after bin assignment

* Carry sum of numeric attributes into the bins

* Also add mean, min, and max

* Add --calculate-feature-index since I keep needing it for testing

* Add an option to accumulate sum/mean/max/min/count of all numeric attrs

* Don't bake in tippecanoe:mean, since we redo it from sum and count

* Forgot to update this test fixture after removing tiled mean

* Update version and changelog
