.zoom as a persistent sandboxed directory

[ar-lex]

Is there any reason for creating .zoom in home directory instead of sandboxing it? It seems to not contain any data that should be shared with other apps. Some flatpak'ed apps (like Firefox with .mozilla) have this kind of data persistently sandboxed (--persist=relative/path).

I moved .zoom to ~/.var/app/us.zoom.Zoom/ for my existing installation, then added the following overrides:

> flatpak --user override us.zoom.Zoom --show
[Context]
filesystems=!~/.zoom
persistent=.zoom

Don't see any difference in Zoom behavior, all the configuration is in place.

This issue is related to #18. Your suggested solution was introduced in #199 but later removed in f87bc46, which in turn comes from the beta branch's #217. I recall seeing a regression being discussed somewhere, but @TheEvilSkeleton did not reference any issue in the revert.
