HK: add grub hunt goal (ArchipelagoMW#3203)

* makes grub hunt goal option that calculates the total available grubs (including item link replacements) and requires all of them to be gathered for goal completion

* update slot data name for grub count

* add option to set number needed for grub hub

* updates to grub hunt goal based on review

* copy/paste fix

* account for 'any' goal and fix overriding non-grub goals

* making sure godhome is in logic for any and removing redundancy on completion condition

* fix typing

* i hate typing

* move to stage_pre_fill

* modify "any" goal so all goals are in logic under minimal settings

* rewrite grub counting to create lookups for grubs and groups that can be reused

* use generator instead of list comprehension

* fix whitespace merging wrong

* minor code cleanup
