Hello,

I use your Go API in one of my projects, especially to count the number of pages on PDFs. But I have just encountered a problem with a particular PDF, which does not allow me to count its page count.
By using your CLI, I was able to get the following feedback:

I think the problem is due to the missing font in this PDF, so it is certainly not compliant. Is there a way to relax this validation when using the API directly in a GO project?

Thank you for your help
