Document support for PMTiles

[louwers]

PMTiles support for MapLibre Native was merged with maplibre/maplibre-native#2882 from @tdcosta100. Built-in support will be available in the upcoming releases for iOS and Android.

I want to document support for it in the MapLibre Style Spec documentation.

Is mbtiles documented as part of the spec?
I tend to think it should be part of native docs only...?
IDK...

This is written in the MapLibre Style Spec Docs now:

A vector tile source. Tiles must be in Mapbox Vector Tile format.

Which is incorrect.

I can also document MBTiles.

[HarelM]

Tiles in pmtiles and mbtiles are in MVT format for a vector source... This is still correct...

[louwers]

OK yes, fair enough. Later it says:

An array of one or more tile source URLs, as in the TileJSON spec.

TileJSON keeps open ended what formats are supported.

An array of tile endpoints. {z}, {x} and {y}, if present, are replaced with the corresponding integers. If multiple endpoints are specified, clients may use any combination of endpoints. All endpoint urls MUST be absolute. All endpoints MUST return the same content for the same URL. The array MUST contain at least one endpoint. The tile extension is NOT limited to any particular format. Some of the more popular are: mvt, vector.pbf, png, webp, and jpg.
