Description

Look into ways to make auto-refresh feasible performance wise. Can be done by implementing PoC testing different approaches and parameters.

Ideas:

Debounce based on coordinate and zoom.
Heavily round the coordinates, so they are only different when the map is moved a lot.
We might want to play with the radius calculated to fit the bounding box. If it's a bit bigger we might not need refresh if the box moves just a little.

One thing we could start experimenting with in this context would be storing the areas from previous requests. The library offers checks for overlapping areas, so we could check if a new request would overlap with what we already have and then don't do a request.
