FreeBSD Port: www/iridium update + www/ungoogled-chromium request

[Master One]

Hello,

I've just seen on FreshPorts that Iridium browser is shown with version
2019.04.73_2 (which is the release from 10th April) last updated on
2019-11-07 although version 2019.11.78 has been released on that same
day:

https://github.com/iridium-browser/iridium-browser/releases

May I use that opportunity to suggest a port of ungoogled-chromium as
well, because it is considered the superior version of a Google free
experience:
