Use transposed direct form 2 for the UHJ all-pass filters
...
This has one extra multiply, but avoids two moves and uses almost half as much
memory for the encoder state.

Remove the extra scaling on W for UHJ encoding
...
There seems to be some inconsistent info about whether W should be scaled by
sqrt(2) for encoding. Not applying the scaling results in a wider stereo image,
which seems more appropriate.
