Tile ID + border visualization

[MisterGC]

I want to be able to see the tile borders and ids/coordinates directly visualized on the globe.

Acceptance:

• shows borders and ids
• visualization can be toggled
• uses mapget tiling scheme

Rersources:

• https://cesium.com/learn/cesiumjs/ref-doc/TileCoordinatesImageryProvider.html
• https://sandcastle.cesium.com/?src=Imagery%20Layers%20Manipulation.html

Additional thoughts:

• How to allow styling and a later stage, for example color tile surface on a specific color based on some rule?
• Will users be able to inspect tiles? Tile properties? Are they separated from this visualization or do they play together?
