Handling deprecated 4CCs

[podborski]

Summary

Some 4CCs have been deprecated (e.g. mere) but those are still registered at mp4ra (and this will stay like that). Some of those appear in this warning message:

we need a way to deal with deprecated ones. Perhaps adding an optional deprecated flag to json files would be an option.

Steps to reproduce

No response

We would need to modify the schema to not allow for other properties when deprecated: true is present. Related
