feat: add isp names and regions to header output

Closes #7. @jimaek, let me know if the output looks good before I merge this.

No tag

With tag

Will also make a corresponding PR for the Slack and Discord bots.

I think the region name should go in () to separate it from the rest since it's a special kind of field and directly applies to the ISP name
