The Witness: Hint distribution changes, added locations, misc fixes

[NewSoupVi]

Changes:

• Hints should feel a lot less same-y now ("Priority hints" are no longer always hints in disguise)
• Keep Hedge Mazes 1-3 and Pressure Plates 1-3 are added as locations in all settings
• Desert Final Room Hexagonal & Desert Final Room Bent 3 are added as locations
• Entries in exclude_locations that are referring to panels are now sent through slot data. This means they can be pre-skipped on the client side.

Fixes:

• Logic error in the Stoneworks that led to more restrictive seeds than necessary
• Logic error for Theater Flowers EP that led to more restrictive seeds than necessary
• Fixed crash in plando when "item" is a dict with weights
• Spoiler log locations were in random order per region, now they are consistent

I think this is fine, but we really should not add new features while RC5 is out :S

I know it's convenient like this, but it might be better to separate fixes from features in the future, because fixes are more reasonable to merge during RC phase.

That's fine with me in this case. This PR was not intentionally timed to be during an RC phase. Bugs that actually break things badly I've been PRing individually the moment I fix them.
I'll be more clear in the future when I include fixes as a part of a bigger content PR bc I didn't deem them an "emergency"

I know it'd be preferrable if all fixes, no matter how small they seem to me personally, came in seperate PRs. But this is the compromise I'm currently willing to make :P
