Begin work on the Kanto Safari Zone.

Some maps are broken up or edited to allow for seamless transitions instead of needing several warps. (Area 1 is split vertically, Area 2 needs a horizontal split. The connection between area 1 and 2 also will have to be shifted up from where it is in RBY to prevent border blocks showing up where they shouldn't.)
