Feature Request: Add support for projections not supported by Leaflet

See original GitHub issue

The Proj4Leaflet Javascript library adds support for additional projections in Leaflet, beyond the standard projections. Could this also be added to IPyLeaflet so that non-standard projections could be requested? For example:

map = ipyleafletee.Map(
  crs='EPSG:3020',  # http://spatialreference.org/ref/epsg/wgs-84-antarctic-polar-stereographic/
  zoom=6,
  center=[0, 0],
  default_tiles=ipyleaflet.TileLayer(url=SOME_URL_THAT_RETURNS_PROJECTED_TILES)
)
map

There is no particular reason not to support it, and it would be great to have. I investigated the use of Proj4Leaflet with vector tiles (that we now have in ipyleaflet), which would have been really nice, but it doesn’t seem to be possible (https://github.com/kartena/Proj4Leaflet/issues/173). If you want to work on that, that would be awesome.

I was going to open this issue but it’s already open so, is there any reason why this is not supported? I think a lot of people work with non standard projections and it would be nice-to-have feature. I can work on it and send a PR for next week.
