The specification does not allow multiple bits to be set,
but some encoders do it anyway.
Applying it only to the first seems to give better results.

The added checks are mostly to handle duplicate frames, which
we discard, thus there are also no P frames for example.

If the height is zero, the decompression will probably end up
failing due to not fitting into the allocated buffer later
anyway, so this doesn't need any more elaborate check.

The sample buffering logic does not take into account that the blocksize
could change. Reset the buffer if the channel configuration changes,
since if there are leftover samples, it is most likely a broken or
misconcatenated stream. This could lead to negative numbers for
missing_samples during decoding.
Thanks to Michael Niedermeyer for pointing these out.
