Normally frequency-matching is only necessary between two channels at a time (a generator and a readout). There are some niche cases (like the example in #236 with analog mixing only on the ADC side) where you might need to do frequency-matching between three things, like a generator, a readout, and an LO source.
This makes a few tweaks (to methods that aren't usually used directly by users) to make that easier.
