* 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
