Add Ilastik

[j6k4m8]

Work in progress. Just here for transparency's sake

• [x] Ilastik scripts( #8, #7 )

• [x] Add Ilastik wrapper

  Chose python for this instead of bash because there's no guarantee we're using bash (although it's pretty likely) and there's zero requirements aside from python's standard libs.

• [x] Make Ilastik talk to LONI ( #7 )
• [x] Converters to and from TIFF/OCP ( #6, #5 )
