Raw coord output addition for Python script conversion to .vox format

Hello Brent! I saw your project on twitter and thought it was really cool. I decided to write a Python script that converts raw voxel coordinate data from Voxel Automata Terrain states to .vox format which is used by Magica Voxel. But I had to add that functionality before I had anything to convert... I am running into an issue that I have outlined below; could you take a look at that and tell me what you think? Thanks!

Added raw coord output functionality, writes a text file with “f” keystroke case. For some reason the output file for larger states (L > 5) and for densely populated smaller states (L <= 5) gets cut off. This is my first time using Java, but as far as I can tell this isn’t an output buffering problem… Any ideas?
