[wip] feat(map): dump nearby exits too

[blacha]

The levelX and levelY are off and need to be fixed.

for example in blood moor

{
  "id": 1,
  "type": "exit",
  "x": 4240,
  "y": 6000,
  "name": "Rogue Encampment"
}

where everything else is a relative position to the blood moor origin { "x": 4520, "y": 5320 }

fixes #414

@blacha there is anything we can do for fixing this offset? What is it relative to?
