LXQt archiver: set password always possibile

[stefonarch]

When creating for example a tar.gz archive it's possible to set an passwd even if neither .tar nor .gz has this feature afaik. Probably true for others too.

Expected Behavior

Passwd field should be deactivated if archive format doesn't support it.

Possible Solution

Check for features when selecting suffix/format

System Information

git checkout of lxqt-archiver, arch

Logical. We should see that, in addition to 7z, which supported archive formats accept passwords.
