Kdenlive needs MLT 7 package

Hi everybody!

MLT 7 has been released about two weeks ago (https://github.com/mltframework/
mlt/releases/tag/v7.0.0). MLT is Kdenlive's mediabackend and one of the main 
dependencies. We want to port Kdenlive from MLT 6 to MLT 7 for version 21.08. 
However our GitLab pipeline is based on openSUSE Tumbleweed (https://
invent.kde.org/sysadmin/ci-tooling/-/blob/master/system-images/suse-qt515/
Dockerfile) and we are now waiting for openSUSE to release MLT 7. Do you have 
any plans when this will happen so we can arrange our schedule after it?

The packages we need for the pipeline are (with MLT 6):
libmlt-devel libmlt++-devel libmlt6-modules libmlt6-data

Cheers,
Julius Künzel from the Kdenlive dev team
