Broken link in README.md in Extraction Requirements

Broken Link!

Inside the Extraction Requirements section. The link for antiword is broken.

DOC extraction requires antiword be installed, [link](http://www.winfield.demon.nl/), unless on OSX in which case textutil (installed by default) is used.

This is the broken link - http://www.winfield.demon.nl

I have attached a screenshot below.

My system specs

Browser - Opera GX Gaming browser.
CPU - Intel i7-6700
Network speed - Down:947.85 Mbps, Up:923.13Mbps

I can fix the link and open a PR for it.

This website has been unavailable for several years, and to the best of my knowledge and search attempts no other location exists for the sources of antiword.

The last state of the original antiword website can be found via the wayback engine:

I found a fork of antiword application. Oldest available antiword app was forked and some patches were incorporated according to the owner of this repo.
