qpeg should probably be changed to use the checked bytestream reader.
But for now this fixes it and is significantly less work.

memcpy() inside the function.

would generate invalid reads.

This fixes clipping if the encoder input used the full 16 bit
input range (samples with a magnitude below 16383 worked fine).
The filtered subband samples should be 15 bit maximum, while
the code earlier produced them scaled to 16 bit.
This makes the decoder output have double the magnitude
compared to before.
The spec reference samples doesn't test the QMF at all, which
was why this part slipped past initially.
