The Alembic importer now works with local coordinates. Previously, the importer converted transformations from Alembic to world coordinates before processing them further; this processing often included re-converting to local coordinates. This change made it possible to remove some code that assumed that a child transform was only read after its parent transform. Blender's Alembic code follows the Maya convention, where in the zero orientation the camera looks forward instead of down. This extra rotation is now handled more consistently, and now also properly handles children of cameras. This fixes T73269. Unit tests were added to at least ensure that the importer and exporter are compatible with each other, and that static and animated camera transforms are handled in the same way.
