Fixes #234, based on work upstream by @gadomski 🙏

Describe this PR

• stac-map is pretty neat.
• This frontend is basically good to go imo.
• We just need to add a few more tweaks on top to implement feature parity with the old frontend, and align with work by @cgiovando on https://github.com/cgiovando/oam-frontend/

Screenshots

Alternative Approaches Considered

• We could use https://github.com/cgiovando/oam-frontend/, and still need to discuss pros / cons.
• But I would love to have this as a community collaborative effort. stac-map is generally useful to many people outside of OAM.
