Use micro for kick-in detection

From watching the stream it seems like on could use the microphones to hear what the referee says in "kick-in", if the microphones are good enough. Not sure how good they are and if that works, feel free to close the issue if it is unrealistic.

I really like this idea. I fear however this only works with good referees who do loud and clear calls. Also I do not know whether the rules require this communication between referee and game controller controller. For example, at GORE 2023 we used headsets instead of shouting.

According to the rules the referee "announces this by calling ..." which implies a loud vocal announcement, which technically made the GORE not rule compliant.

However, I would point out that while I personally also like this idea there may be more exception and risks with this:

1. Referee calls wrong color then corrects themselves
2. Referee calls game state and then uh huh um color, how do we detect that (in)coherence between words?
3. Audience members call stuff out that they think is correct #HTWK
4. The game announcers if available are much louder than the referee if they have microphones.

I think this should be honestly considered when and if we have proper sound localization (which we desperately need for whistles anyway) so that we can determine if this is a likely call from the referee of the field we are playing on.
