iam happy with either openhevc picking this version or us picking
the one from openhevc with minimal changes needed to make it work for
Though in the first case we should pick the openhevc version and
comit our changes in a seperate commit on top so openhevc can
more easily pick the changes we made if they want to.

either way i hope very much that openhevcs and our implementation
could stay similar as divergence would mean duplicated maintaince
effort and both projects would have to do extra work in picking
changes from the other
