[Feature]: Trusted timestamping

[makew0rld]

Context

Currently WACZ files created with Browsertrix are timestamped using trusted timestamping, proving the date they were created and locking their content in time.

What change would you like to see?

It would be cool to have this feature available to non-cloud web archives created by users with ArchiveWeb.page. I figure this would require some re-architecting since Authsign can't be used, but I think providing this kind of integrity guarantee would be really great. It would make independent web archives much more trustable.
