Suggestion: Github Cleanup (Branches, tags, some history leftovers)

I think this branches can be safely deleted

ofThreadChannel-trySend
bugfix-hdv

some tags can be cleaned to and kept for releases or intermediate builds

and recently I've cloned the openFrameworks repo to list the top 20 largest files in there, and it seems almost none should be part of the distribution anyway. here is the command

git rev-list --objects --all \
  | grep "$(git verify-pack -v .git/objects/pack/*.idx \
           | sort -k 3 -n \
           | tail -20 \
           | awk '{print$1}')"

and the result

Start by reviewing the proposed branches ofThreadChannel-trySend and bugfix-hdv, the release and intermediate-build tags, and the large objects under addons/, libs/, and libs/openFrameworksCompiled/. Run the listed git rev-list/git verify-pack command to reproduce the inventory. Done means the repository cleanup scope is agreed and the selected branches, tags, and history or distribution leftovers have been safely addressed.
