no problem: put 0 as the 32nd bit :-), or
extend the code by one bit (this is pretty standard in block codes).
In the case of rate-1/2 CC you just run the encoder for 16 steps so you get exactly 32 bits out.

When the --use-whitener-offset option is chosen, we're actually using
all 16 bits of the field (the upper nibble is the 4-bit whitener
offset), so we'd need a (32,16) code, if such a thing exists.
