hosts: Add nvr0.p.b

*nvr0.pyrocufflink.blue* hosts Frigate.  It is deployed on a separate
subnet, for two reasons:

* To avoid streaming video from the cameras through the firewall
* To prevent any hosts on the LAN except Home Assistant from
  communicating with Frigate, since it does not have any kind of
  authentication or access control
