Bug instantiating gimp file with GimpDocument. Seems like its an issue with changes to str and bytes.

from gimpformats.gimpXcfDocument import GimpDocument
imagepath = 'borders.xcf'
doc = GimpDocument(imagepath)

Produces the follow dump:

Traceback (most recent call last):

TypeError: a bytes-like object is required, not 'int'

It looks like it's likely caused by changes to bytes and str and between old and newer version of python. I'll update this "issue" as I get more detailed information. In the meantime, I'm sure you must already know or is this possibly a dead project?

If you wanna make a pull request that'd be very much appreciated. Also it might be worth taking a look at #1 as this is where my thoughts are regarding the future of the project

Think I've fixed it

If this is still broken then can you send me the xcf file and I'll take another look sometime

Thanks
