// - the requested channel is the first (0) or the following (just 1 in BladeRF 2 case)
//
// The BladeRF support library lets you work in two possible modes:
// - Single Output (SO) with only one channel streaming. This HAS to be channel 0.
// - Multiple Output (MO) with two channels streaming using interleaved samples. It MUST be in this configuration if channel 1
// is used. When we will run with only channel 1 streaming from the client perspective the channel 0 will actually be enabled
// and streaming but zero samples will be sent to it.
//
// It manages the transition form SO where only one channel (the first or channel 0) should be running to the
// Multiple Output (MO) if the requested channel is 1. More generally it checks if the requested channel is within the current
// channel range allocated in the thread or past it. To perform the transition it stops the thread, deletes it and creates a new one.
// It marks the thread as needing start.
//
// If the requested channel is within the thread channel range (this thread being already allocated) it simply removes its FIFO reference
// so that the samples are not taken from the FIFO anymore and leaves the thread unchanged (no stop, no delete/new)
//
// If there is no thread allocated it creates a new one with a number of channels that fits the requested channel. That is
// 1 if channel 0 is requested (SO mode) and 2 if channel 1 is requested (MO mode). It marks the thread as needing start.
//
// Eventually it registers the FIFO in the thread. If the thread has to be started it enables the channels up to the number of channels
