Add config option to ignore bad SSL certs when archiving

[pirate]

In the modern age of HTTPS everywhere, it's becoming increasingly common for sites to set up SSL badly or forget to renew their certificates (especially older 90's era sites), rendering the sites inaccessible.
When browsing I always want to be alerted of bad certs, but when archiving 90% I want it to attempt archiving cites with bad certs anyway in case the content is important. After all, archiving a certificate error page is useless 100% of the time, so instead of throwing out hands up and skipping the site it's nice to at least attempt getting a snapshot.

TODO:

• Add option to skip checking SSL certificates for validity
• Implement fetch_wget cli option to skip cert check
• Implement fetch_pdf cli option to skip cert check
• Implement fetch_screenshot cli option to skip cert check

Last two steps just require doing some research on the chrome headless command line interface to find the right flags.

I am a beginner and would like to work on this issue. Can i take it up and be guided along?

Yeah, go for it @ShubhGupta2125 ! The next steps are to figure out how to make chromium-browser ignore SSL errors using a command line flag or some other setting.

I implemented this a little while ago, but thanks for your help @ShubhGupta2125
