Command in the readme for fetching jbovlaste fails due to captcha

[zenhack]

The wget command in the readme fails to fetch jbovlaste; the xml export presents a captcha to the user if they are not logged in.

I've added a script to act as a workaround for the captcha. It will log you into jbovlaste with your credentials, avoiding the captcha. The readme has also been amended to say to use the script rather than wget.

Sorry for my slow response. The other solution is to log into jbovlaste, extract your login cookie from the browser (it never expires), and provide that to the script instead. I have local changes related to this that I really need to get around to pushing. I'll leave this open to remind me.

Seems fixed. This is nolonger a manual step as the docker container is able to fetch the XML file without requiring to complete a captcha.
