NOTE: This is a WIP (Draft status), so is likely to be buggy.

The following has been modified:

• on school focus, panning to center happens only if school is out of bounds
• on useEffect (when any of selectedSchool, mapLoaded, flyToOptions*, userHasInteracted change), panning (or jumping) to center happens only if school is out of bounds

Closes #259

*is static, so candidate for removal

Potential TODOs for this or future PR:

• consolidate some of the panning / jumping code
• look for opportunities to combine the focus handler and the useEffect
• instead of just checking for "out of bounds", also check if school is topmost element
• make sure bottom of school marker is visible (ideally, adjust bottom of marker to be centered on school's lat/lng)
