Initial giant enby Commit

- Changed name lists
- Made Overworld pink palette into purple palette
- Changed gender selection options
- Added Topaz's graphics (Enby Trainer)
- Changed more or less every gender check in the game to account for enby option
- Changed out Morty's palette on  the trainer card to a more purple one to facilitate Topaz's graphics

KNOWN ISSUES / THINGS TO CHANGE
- Topaz's sprite does not currently render correctly on town map (check if this is a map issue or if it occasionally will pop up elsewhere as well)
- Bag Palette is still green like the tutorial made it. Might change it to yellow or something later on.
