Add FGLR Lucky Egg Farmer

[Dalton-V]

This adds a Lucky Egg Farmer for FRLG

This program is dependent on the WildEncounterReader in #1135

New Detectors

• PartyHeldItemDetector used to detect if a captured Chansey is holding a Lucky Egg
• BattleSelectionArrowDetector the selection arrow in battles is slightly different from the start menu arrow. This new arrow is also used when asked for a nickname.
• PokedexRegisteredDetector this detects the "A" button in the bottom right when a new pokemon is added to the dex. (Used if the player has not captured Chansey before.

Updates to existing logic

• Safari Zone has a different start menu layout from the standard overworld.
• Updated the Start Menu navigation to search the whole area for the selection arrow instead of multiple watchers as mentioned in a previous PR.
