Series rev-parse: implement object type filter | expand

Commit Message

Patrick Steinhardt March 1, 2021, 12:20 p.m. UTC 
Object filters currently only support filtering blobs or trees based on
some criteria. This commit lays the foundation to also allow filtering
of tags and commits.

No change in behaviour is expected from this commit given that there are
no filters yet for those object types.
