Supporting MVT-like vector tiles? about xyzservices

[martinfleis]

There's certainly a willingness to add support for vector tiles. There was no discussion on how to do that. They will probably need more information than we store for XYZ.

We also need to find a way how to distinguish between the tile types since other libraries are now expecting that xyzservices.providers is a bunch of XYZ tiles. If we just added vector tiles with an attribute type="vector" it may cause some friction (you'd need to first filter xyz types...).

If you have any ideas I am all ears.
