Quite frankly, wouldn't it be nicer to just make CCR be about which
*cylinder* you are breathing, making the "dive mode" change be just a
cylinder change event.

.. and basically add a "CCR vs OC" to the cylinder information.  And
we already track everywhere what the active cylinder is, so looking up
"what's the dive mode right now" is just a question of looking at the
state of the active cylinder.

Don't we want to do do that anyway for other reasons? I thought people
wanted to track their O2 and diluent gas use anyway...
