Disappearing boxes

@hohonuuli fyi -- just entering the issue here ; )

A fragment from @kevinsbarnard screencast demonstrating the issue:

• significant improvement with a smaller period for MediaPlayerTimer: 10ms (previously 100ms)
• boxes a more consistently being displayed (though it would be nice if we had a "move" operation that could avoid the increased flickering due to the more rapid updates)
• The mediaPlayer library (vcl4j) does not provide a consistent result when querying for the status of the media being played or paused. That is, with the media actually playing, the call mediaPlayer.status().isPlaying() (used by MediaPlayerTimer) switches back and forth, that is, with one true then a number of false returns in sequence, then true again and so on.

Here's how the result of an initial set of adjustments looks like:

Hmm, but the screencast (captured using Camtasia) doesn't really seem to reflect the more frequent updates noted on Cthulhu itself.

I've updated Cthulhu's source so it runs on M1/arm as well as amd/x86. I've been running tests on it with boxjelly and everything is working really well with the disappearing-boxes branch. I'm going to take this with a grain of salt as the M1's performance might be enough to hide subtle performance problems.

Let's then close this one per https://github.com/mbari-org/cthulhu/pull/21
