Fixed some entrances that require reset otherwise
Fixed TR lobbies that need to be bombed
Fixed animated tiles in lobbies
Fixed wallmaster+lamp problem
Fixed some key rules that caused item requirements to be ignored
Fixed Old Man cave to be properly one-way in the graph
Fixed some odd key logic issues
-Added a bunch of crystal switch logic
-Added a check for maiden backtracking
-OrderedFrozenSet to prevent randomization leaks with the same seed
-A few key improvements from an outstanding PR
-Rewrite of step 3b for accuracy - verified acceptable speed
--Can now detect an impossible balance situation and restart
-Eliminated false negatives in step 4 (still need to rework false positives)
-Minor key logic improvement
--Introduced reachable_switches
--Calculate total completion in equation resolution
--Prioritized one-way connections over neutral/neutral_profitable sectored but not over dead-ends
--Simplified finding good complex branching candidates - just re-used equations routine
--Valid multi choice for global polarity when fixing parity
--Added total dungeon charge as critieria when fixing parity
--Pinball used for navigation in skull 2, marked appropriately (particularly with Ice Cross in Skull 2)
--Equation resolution detects used benefits with unreached_doors benefits
--Greedy equation finder not longer used destination/entrance sectors of the wrong split dungeon
--Required connections don't overestimate benefits
--Introduced the concept of crystal switches and doors blocked by blue barriers to equations
