Add URIs to output

[Tholep]

During my working with PDF, I usually see fishing emails having URIs which leads to malicious sites. Hence, it is beneficial to analysts when found URIs are displayed in the main output and in "info" command

Hi @Tholep,

Thanks for the PR. When you mention URIs in main and info command, do you mean showing the specific URIs there? Because there is already an URI element there, and you can see the URIs executing "extract uri"...

thanks for your reply. I don't mean to display specific URIs, but I prefer to display found URIs in the output when executing "peepdf.py a_pdf_file.pdf".
