Transition Randomization

[jet082]

This is probably a big ask, so feel free to ignore or put on the backburner for a very-distant feature.

It would be nice to have the https://github.com/Shop-kins/TransitionRandomiser supported in some capacity or another so as to enable logical region randomization. I'm unsure how this would impact the logic.

Something for the far-off future maybe. It would require the logic to move away from using depth as its primary indicator of progression. That does kinda tie into #41 too.
