feat: Automatically detect Reolink NVR channel number (#2259)

- Closes: #2032, #1899 
 -  May or may not help with #2254

- Caution: I do not have an NVR-based Reolink camera to test. If
suddenly Reolink cameras don't work in the card, or in particular if
media doesn't correctly load, this is likely the culprit PR.
