ValueError: too many values to unpack (expected 2)

Ran prosopopee directly in the example/ directory and it throws the following error

Traceback (most recent call last):

    width, height = out.decode("utf-8").split(",")
ValueError: too many values to unpack (expected 2)

out.decode("utf-8") returns 1920,1080, so naturally the second comma makes it so that that out.decode("utf-8").split(",") returns ['1920', '1080', ''].

As a stopgap I change the line to

width, height = out.decode("utf-8").split(",")[:2]

and prosopopee terminated normally.
