Support anti-meridian crossing AOIs in `split_area`

[VincentVerelst]

_job_splitting.split_area will currently fail on an AOI that crosses the anti-meridian. Extend the functionality to be able to handle this correctly.

in what way does it fail? Empty result or some kind of exception?

Ah, this issue is also being handled in #886
