VectorGridProtobuf not working properly with LayerControl

[giswqs]

Describe the bug
The VectorGridProtobuf example works fine with the layer control. However, once the layer control is added, the vector tile layer can no longer be overlaid on the basemap layer. I am not sure if this a folium plugin problem or the upstream leaflet.VectorGrid.Protobuf issue.

@iwpnd

import folium
import folium.plugins as plugins

url = "https://tile.nextzen.org/tilezen/vector/v1/512/all/{z}/{x}/{y}.mvt?api_key=gCZXZglvRQa6sB2z7JzL1w"
m = folium.Map(location=[46.8, 8.2], zoom_start=14)
vc = plugins.VectorGridProtobuf(url, "vector tile")
vc.add_to(m)
folium.LayerControl().add_to(m)
m

Expected behavior
A clear and concise description of what you expected to happen.

Environment (please complete the following information):

• Python version: 3.9
• folium version: 0.14.0

Additional context
Add any other context about the problem here.

Possible solutions
folium.TileLayer has the overlay argument that allows overlaying layer. Can VectorGridProtobuf have the same?

This looks to be on layer control as you're selecting either tiles or background and not both.

[giswqs]

The layer control shows the layers as radio buttons. You can only select on layer at a time, not both.

[giswqs]

Ideally, the vector tile layer should be listed with a checkbox next to it, not radio button.

Thank you for the pointer @giswqs, I found the issue and will be providing a PR with a fix asap

The issue is resolved with #1723 once merged.
