This patch replaces the transform used in AAC with lavu/tx and removes the limitation on only being able to decode 960-sample files with the float decoder. This commit also removes a whole bunch of unnecessary and slow lifting steps the decoder did to compensate for the poor accuracy of the old integer transformation code. Overall float decoder speedup on Zen 3 for 64kbps: 32%
