That's a very good suggestion.
Since the main problem with M/S and IS was phasing this might be a way to
solve that too.

Yes, that's what I remember too from testing it too.

That previous idea discriminated way too many bands for it to be actually
useful. And it would require special cases for coefficients which 'blow up'
and have an insane value.
This method is naive but it handles spikes better since a single spike in
one channel will only cause a single phase to sw

This commit adds a slightly more robust way of determining whether the phases
match or are too different for IS to be used.
