Vermilion Officer Jenny, other things

- Adds Officer Jenny from Yellow to Vermilion City. Due to spriteset restrictions, Roingus Girl has been removed; the self-insert felt a little weird anyway.
- Fuchsia City's map has been redone a little bit to more closely resemble the LGPE version, being far more walkable and aesthetically appealing.
- A Firefighter has been added to Cerulean Gym!
