Update OpenGoPro camera list to include serial number prefixes

[mmarich]

It would be useful to also list the serial number prefixes for each supported camera model listed here:

https://gopro.github.io/OpenGoPro/

Serial number prefixes are currently provided in a GoPro community article here:

https://community.gopro.com/s/article/how-to-identify-your-gopro-camera?language=en_US

The community article does not list values for the Hero13. Maintaining this information as part of the OpenGoPro documentation would be valuable to developers.
