core: Generic boss plando handler (#1044)

* fix some blunders i made when implementing this

* move generic functions to core class

* move lttp specific stuff out and split up from_text a bit for more modularity

* slightly optimize from_text call order

* don't make changes on github apparently. reading hard

* Metaclass Magic

* do a check against the base class

* copy paste strikes again

* use option default instead of hardcoded "none". check locations and bosses aren't reused.

* throw dupe location error for lttp

* generic singularity support with a bool

* forgot to enable it for lttp

* better error handling

* PlandoBosses: fix inheritance of singularity

* Tests: PlandoBosses

* fix case insensitive tests

* Tests: cleanup PlandoBosses tests

* f in the chat

* oop

* split location into a different variable

* pass the list of options as `option_list`
