[Bf-committers] Alembic upgrade from 1.7.8 to 1.7.12

[Sybren A. Stüvel]

Dear platform maintainers,

I've just bumped Alembic from 1.7.8 to 1.7.12. This is not a
needs-to-be-updated-right-now update, but it does add some functionality
people have been waiting for a long time :-)

Some context: Alembic 1.7.12 introduces a 'DCC FPS' hint, allowing
Blender to write the scene frame rate to the Alembic file. This will
make it possible for importers and converters to properly deal with
situations where 'frame number' is the only reference to time. It should
prevent issues like described in T55288, where Blender wrote correct
data to Alembic, but the importing software made bad assumptions because
it hard-coded 24 FPS.

Currently only the Alembic library is upgraded from 1.7.8 to 1.7.12.
Writing this new DCC FPS hint will be done in a separate commit once the
platform libraries have been updated.

Cheers,
