Examine raw MVT tiles, perf, better .mbtiles support
Examine MVT tile content
debug-mvt and mbtiles-tools can now decode MVT tile content, either as a summary table or in an extended view, with optional language names lists.
The tile can be retrieved from Postgres (using layer definition yaml file), from a url/file/STDIN, or from an .mbtiles file (#273, #274) - @nyurik
$ debug-mvt dump "https://tiles.maps.elastic.co/data/v3/6/17/23.pbf" --summary
Uncompressed tile from https://tiles.maps.elastic.co/data/v3/6/17/23.pbf size=68,765 bytes, gzipped=39,095 bytes, 8 layers
