Certain images cause athenapdf to crash

[ahgilbert]

We are using athenapdf to render documents that include image assets provided to us by our clients. Some of these images reliably cause AthenaPDF to crash with the message:

v2: The renderer process has crashed.
v3: athenapdf: error: nil response received

To reproduce, render the contents of this gist through athenapdf version 2 or 3.
