TUNIC: ER Refactor for better plando connections, fewer shops improvement (#3075)

* Fixed shop changes

* Update option description

* Apply suggestions from Vi's review (thank you)

* Fix for plando connections on a full scene

* Plando connections should work better now for complicated paths

* Even more good plando connections yes

* Starting to move the info over

* Fixing up formatting a bit

* Remove unneeded item info

* Put in updated_reachable_regions, to replace add_dependent_regions

* Updated to match ladder shuffle

* More stuff I guess

* It functions!

* It mostly works with plando now, some slight issues still

* Fixed minor logic bug

* Fixed world leakage

* Change exception message

* Make exception message better for troubleshooting failed connections

* Merged with main

* technically a logic fix but it would never matter cause no start shuffle

* Add a couple more alias item groups cause yeah

* Rename beneath the vault front -> beneath the vault main

* Flip lantern access rule to the region

* Add missing connection to traversal reqs

* Move start_inventory_from_pool to the top so that it's next to start_inventory

* Reword the fixed shop description slightly

* Refactor per ixrec's comments

* Greatly reduced an overcomplicated block because Vi is cool and smart and also cool

* Rewrite traversal reqs thing per Vi's comments
