The most serious issue this PR addresses is that entrances that use doors without items (a small subset of doors when door shuffle is on, but *every* door when door shuffle is off, which is the default) underestimate the requirements needed to use that entrance. The logic would calculate the panels needed to open the door, but would neglect to keep track of the rooms those panels were in, meaning that doors would be considered openable if you had the colors needed to solve a panel that's in a room you have no access to.
Another issue is that, previously, logic would always consider the "ANOTHER TRY" panel accessible for the purposes of the LEVEL 2 panel hunt. This could result in seeds where the player is expected to have exactly the correct number of solves to reach LEVEL 2, but in reality is short by one because ANOTHER TRY itself is not revealed until the panel hunt is complete. This change marks ANOTHER TRY as non-counting, because even though it is technically a counting panel in-game, it can never contribute to the LEVEL 2 panel hunt. This issue could also apply to THE MASTER, since it is the only other counting panel with special access rules, although it is much less likely. This change adds special handling for counting THE MASTER. These issues were possible to manifest whenever the LEVEL 2 panel hunt was enabled, which it is by default.
Smaller logic issues also fixed in this PR:
* The Orange Tower Basement MASTERY panel was marked as requiring the mastery doors to be opened, when it was actually possible to get it without them by using a painting to get into the room.
* The Pilgrim Room painting item was incorrectly being marked as a filler item, despite it being progression.
* There has been another update to the game that adds connections between areas that were previously not connected. These changes were additive, which is why they are not critical.
* The panel stacks in the rhyme room now require both colours on each panel.
Almost all of the events have been eradicated, which significantly improves both generation speed and playthrough calculation.
Previously, checking for access to a location involved checking for access to each panel in the location, as well as recursively checking for access to any panels required by those panels. This potentially performed the same check multiple times. The access requirements for locations are now calculated and flattened in generate_early, so that the access function can directly check for the required rooms, doors, and colors.
These flattened access requirements are also used for Entrance checking, and register_indirect_condition is used to make sure that can_reach(Region) is safe to use.
The Mastery and Level 2 rules now just run a bunch of access rules and count the number of them that succeed, instead of relying on event items.
Finally: the Level 2 panel hunt is now enabled even when Level 2 is not the victory condition, as I feel that generation is fast enough now for that to be acceptable.
