Increasing the value at low rate seems to help a bit.

Otherwise, we risk having "temporal holes" in the HF that anti-collapse
can't always fill in.

It would trigger on the second frame of "S"s, causing holes in the spectrum

That was likely a mistake from a misunderstanding on the SILK bit allocation

Hybrid CBR now simply forces the SILK CBR rate to the "target" value. Also,
we're getting rid of the -2 kb/s offset for CBR, which appeared to be harmful.
In the case of hybrid constrained VBR, the cap is computed in the same way
as the target.

The NSQ SSE optimizations are disabled for now because they need to be updated

Only complexity 0-1 now uses the plain non-delayed-decision NSQ since its
quality is pretty bad. Previously 0-3 were using that plain NSQ.

Previously, the bandwidth detection could (e.g.) change the bandwidth
from fullband to superwideband, and the hysteresis would then cause
bandwidth to be stuck in superwideband.
