Reworked the static modes. Now, if all static modes have the same frame size,
...
overlap or number of channels, we can pass the hint to the compiler.

Rework CWRS code.
...
This eliminates an extra O(nm) lookups on decode, and reduces the rate control
from O(nm^2) to O(nm), in addition to eliminating O(m) lookups on both encode
and decode.
Although the interface is slightly more complex, the internal code is also
simpler.
