read blockball map

[vinport16]

right now the testing map sucks and is annoying

• copy over the editor files from blockball into this project and adjust the editor as you see fit
  • maybe preload it with a few colors - I was stumbling around with this before
• link to the editor from the start page (readme)
• create a function that can take in the raw file input for a blockball map (output of map maker) and output a World object
  • declare chunk size when making the map? or declare chunk size when importing?
  • consider centering the world horizontally over 0, and keep the lowest layer at y = 0 or 1
