Change MapboxGL to MapLibreGL

[rogup]

Since we are using the open-source version of Mapbox (MapLibre) in Mykomap, we should use this in LX too.

We currently use this React binding https://github.com/alex3165/react-mapbox-gl but it probably makes sense to switch to this one instead as part of this work, since it's more widely used, actively maintained, and tested with MapLibre https://github.com/visgl/react-map-gl

Switching over should be fairly easy for the most part, but I think there are a few differences between the binding APIs, such as

• how we do clustering
• how we do drawing. This is probably the biggest piece of work, but seems to be possible with some workarounds https://visgl.github.io/react-map-gl/examples/draw-polygon https://github.com/mapbox/mapbox-gl-draw/issues/1182

Estimate: 2.5 days

@lin-d-hop is this something that you think is worth adding to the backlog? The main reason is so that we use more OSS.

@ms0ur1s this probably relates to what you're doing in #317 since that involves draw controls. How's that piece of work going for you?
