Fix is in git. I'll have to plan a release at some point in the near future, but might not be for a couple weeks due to a vacation.

It looks like I've run into two more new problems

1. Exception RangeError (index): Index out of range: index should be less than...
   index should be less than 28926027: 28926027
   index should be less than 11570024: 11570024

2. Exception ImageException: Unsupported compression: ***
   33024, 2569, 5374, 4125, 3856... a huge number of "methods"

The files come out too big, so I had to use google drive

I took out the code that tries to read the actual layers from the PSD, and it will just read the merged image now. PSD is too weird of a proprietary format to handle all those cases, but at least it always provides the merged image. The changes are in git, those images can be read now.
