BOTH resolutions on CH0_0 and CH0_1

[jlopez77]

Hey! Nice job you did. I resurrected an old camera that was never put to use due to the lack of a rtsp server :) Thanks for that!

Could you please release a version with the defaults on BOTH or configurable via config file in the SD? That would be a game changer, for example to use this super cheap cameras with Frigate...

Now it's:

// Setting default int resolution = RESOLUTION_HIGH; int port = 554; int debug = 0;

Could be:

// Setting default int resolution = RESOLUTION_BOTH; int port = 554; int debug = 0;
