Support for FlatGeoBuf

[diegoripley]

I looked through the issues and noticed that you plan to support the standards listed at
#314

Is there a plan to support FlatGeoBuf? I am aware that it might not be the best file standard at higher zoom levels (especially when there are lots of features), but it has better spatial filtering compared to other formats.

This could potentially be paired up with a STAC extension like this one to optimally show the FlatBeoBuf at the right zoom levels, so that the end-user is not overloaded with requests.

I haven't thought about rendering vector layers yet, but there's no reason why we couldn't. #341

The primary issue will be that you'd need to load everything in FGB unless you restrict it to very zoomed in... Once zoomed in it should work fine. Tried to implement it in ol-stac and didn't feel good.

Indeed, I had similar issues in QGIS. Higher zoom levels were fine, lower zoom levels were not.
