Small adjustments and bug fixes

[konstntokas]

• Enhanced the function bbox_overlap so that it can handle bounding boxed crossing
  the antimeridian
• Added new class method GridMapping.regular_from_bbox, which allows creating a
  regular grid mapping directly from a bounding box, spatial resolution, and CRS.
• Bug fix: fixed grid mapping creation for irregular grids with decreasing longitude
  along axis 1.

Checklist:

• Add unit tests and/or doctests in docstrings
• Add docstrings and API docs for any new/modified user-facing classes and functions
• New/modified features documented in docs/
• Changes documented in CHANGES.md
• CI checks pass
• Test coverage remains or increases (target 100%)
