Update to URL library

[Glyn Matthews]

Hello all,

This is a short announcement to say that I have developed an update to what was the URI library:

https://github.com/cpp-netlib/url

It is essentially a re-write of the original library, but now implements the WhatWG specification. More details are in the README file:

https://github.com/cpp-netlib/url/blob/master/README.md

If anyone is interested to test or review it, please let me know. I will also be available on Slack.

Regards,

Glyn
