feat(worldmap): center camera around a designated point

[lowlighter]

Currently the teleportation occurs at map origin, rather than a designated point such as a pkmn center or entrance

Suggested solution:

• Define a "teleportation point" via tiled through a special tile
• Extract it and update teleportation location

Implemented (code-wise) The "location" tile automatically extract a "spawn" point
