No reason, I was just moving stuff about and left it up there. I've moved it back!

This was not achievable as the format would get overwritten as soon as the resample instance was initialized. The translation core now gives priority to translator implementations and falls back to finding or creating a format if that fails. The codec_resample module also assumed it had to release the format reference when in reality this is done by the translation core itself.
