Creates a new voice channel called "Extra Practice Room" if all registered PRs are occupied by either muted or unmuted users. Muted or unmuted doesn't matter because we want to discourage people from using rooms that are occupied even if all the participants are currently muted - it could be the case that someone was practising there but was just muted temporarily.
If the practice rooms aren't full, the bot checks to see if it should remove one of the temp rooms. It will remove a temp room if there are at least two empty rooms, and one of those empty rooms is a temp room. (If none of the empty rooms is a temp room, then the only rooms we can remove are the main rooms, which we don't want to remove. If there is only one empty room, we need that room to be available.)
