From: Adithya Chakilam <achakilam@nvidia.com>
Some external object stores (like key-value) manage and retrieve git
objects individually. Although repack's --filter-to option can separate
objects from the main object store, it writes them into packs. Using
those objects individually then requires an additional unpacking step.
Add --filter-to-loose=<dir> to write filtered-out objects directly as
loose objects into <dir>, treating it as an object directory. Stream
the filtered pack into unpack-objects instead of writing an intermediate
pack file to disk.
The filtered pack is built with --stdin-packs, so this initially handles
only objects already stored in packs. Loose objects in the source
repository are left in place.

--filter-to-loose only writes objects that were in an existing pack,
because the filtered pack is built with --stdin-packs. Loose objects
that the filter excludes stay behind in the source repository, so the
destination does not get the complete set of filtered-out objects.
Copy such loose objects to the destination as well. An object already
present in the destination is not rewritten. With -d, the source copies
are removed once everything is written.
