Generating encounters from an EncounterArea is getting a little stupid
without inheritance; each type can now have its own specific behavior
without checking for each individual type of generation pattern. Will
add the abstract method implementations in a future commit
Move some string[] array fetch (for all languages) to Util
Closes#2381
Keep Raichu and Marowak at the end for ez referencing. Keep a separate
refence for alolan kanto stuff for futureproofing
Might want to improve the EncounterArea abstraction to do the
slot-finding labor themselves, but whatever, hardcode stuff until swsh
throws new monkey wrenches in. A good idea would be a dictionary with
level forcings [species | form << 10] = X and use the dictionary to
check on slot creation
Other games may vary the flawless IV count so best to have consistent
declarations
(the vc transfer encounter has 5 or 3 depending if it's a mew/celebi)
