Support PMTiles in Editor

[ohrie]

PMTiles from Protomaps are increasingly popular and a lot of other services are supporting it now. It has some major advantages in comparison to MBTiles. Styling the PMTiles is, however not possible yet, using the data set directly.

MapLibre GL JS supports PMTiles. Therefore a switch to Maplibre GL JS (see #781) in addition with the support of pmtiles URLs link (like this) would be super cool, so we can use PMTiles in Maputnik!

MapLibre supports this feature with an external plugin that relies on the addprotocol method.

I think that adding this functionality might confuse users who do not know this,
and that may not know that the output of their style will only work under certain tile deployment and development conditions (for example it will likely not work in GeoServer or QGIS)

In my opinion, unless PMTiles are integrated as an official source in the MapLibre Style Sepcification this will likely cause confusion, even though it might be highly beneficial for certain users.

I agree with @bogind, I think it makes more sense to support this as a XYZ URL in Maputnik. It is very difficult to support plugins at the editor level, and it's not a significant workflow difference if you have to substitute one URL.

If and when it's integrated, then we can reconsider.

Now that MapLibre is the rendering engine for Maputnik #812, it would make sense to me that the PMTiles plugin will be added by default to Maputnik, and enable the use of pmtiles:... sources.

I don't think the issue was with the rendering engine, but with the style specification itself.
PMTiles is still an external plugin for MapLibre.

In my opinion (currently as a user, not a contributor), this should not be added, unless with strict instructions and warnings about compatibility. This can cause credibility issues with non-proficient users who would try to use the exported pmtiles:... styles in rendering engines that do not support them.
