Bill's Garden, add Rowan NPC

Rowan NPC added to Cinnabar Lab, just a little cute thing.

Bill's Garden could see many revisions, what's here is the bare minimum. Here's what's done:
- Nidorino NPC blocks it off and is unlocked in the post-game. This currently contradicts the myth - I have a plan for this soon.
- Wild Pokemon are the "non-reproducibles" given in Stadium; starters and eevee are mandatory given those were common in the myth
- Hisui forms should be added when possible
- I had to remake Martha's map in the forest tileset so leaving would be possible
- Everything is at a point where it functions
