VOXELFORMAT: PXO: add Pixelorama format support

[mgerhardy]

pxo is the file format - and this is basically only a zip file with data.json and an image_data folder containing the frames and layers

There is also embedded json in the data.json

node types are

• 0: 2d layer
• 1: group
• 2: 3d layer

data.json <file>
image_data <directory>
  frames <directory>
    1 <directory>
      layer_1 <file>
      layer_3 <file>
    2 <directory>
      layer_1 <file>
      layer_3 <file>
