Serve local tiles with notebook

Today it is not possible to set a path to local tiles, with something like:

l = {'url': 'file:///home/user/path/to/tiles/{z}/{x}/{y}.png'}
m.add_layer(l)

Instead, the directory of the tiles has to be served with e.g.:

python -m http.server --bind 127.0.0.1

And the URL has to be set to http://127.0.0.1:8000/{z}/{x}/{y}.png. Could it be done transparently with the notebook server?

I think it would make sense to add it to ipyleaflet, as a new layer LocalTilesLayer? Or as a helper function get_local_tiles_url(tiles_path)? I guess some people would be happy to have it in ipyleaflet

I opened a PR. I didn’t use your workaround, the reason is that if you are running multiple servers you can’t know which one you are currently using, I guess it could be an issue. So I retrieve the URL on the Javascript side.
