Subject: [PATCH] Extract Chromecast firmware version

Rather than put the CPU type as the OS version, for Chromecast, the
firmware version would be much more useful.

For example:

  Mozilla/5.0 (X11; Linux aarch64) AppleWebKit/537.36 (KHTML, like
  Gecko) Chrome/76.0.3809.81 Safari/537.36 CrKey/1.42.183786

This should produce:

  os: { name: "Chromecast", version: "1.42.183786" }

Instead of:

  os: { name: "Linux", version: "aarch64" }
