More dex entries, Meltan/Melmetal base stats and dex

This finishes the regional form dex entries and adds Meltan and Melmetal to the framework since they aren't in yet.

The following needs to be done:
- Name entry
- Dex placement
- Cries
- Palettes
- Sprites adjusted for KEP itself (greyscale, 56x56, whitening)
- Sizes
- probably a bit more
