Detach/extract pypdf_table_extraction fork

Going to https://support.github.com/contact?tags=rr-forks&subject=Detach%20Fork&flow=detach_fork

I think we should "extract" soon to get rid of this note:

What do you think?

Yes, Extract method makes sense.

On a other project I made the mistake to delete the fork. Making it quite difficult to incorporate the changes of the subforks into the new root.

It is good to show people what things really are: this is a fork.

If we get some more traction we can extract the repo.
