IEEE Float .wav files have almost identical structure
to standard PCM .wav files.  Currently, wave.py gives
an unknown format error when attempting to read IEEE
Float .wav files. This patch causes wave.py to read
those files properly.

No changes were made to wave_write, only wave_read.

I don't know anything about the .wav format, but the patch
is particularly inoffensive... it simply allows a second
format constant in the WAVE header without raising an error.
I recomend applying the patch as soon as someone else who
DOES know the .wav format can confirm that it's being done
right.

Looking at the WAV format description at
http://ccrma.stanford.edu/CCRMA/Courses/422/projects/WaveFormat
, it looks like the patch isn't correct. There's an
ExtraParams field after the header that's only present if
the format is not PCM.  If this is correct, the patch should
also add code to read this field and either store it
somewhere or just discard it.

Since there was no follow-up to Andrew's remark that the patch is incorrect, I conclude that the submitter either lost interest in it, or agrees that the patch is indeed incorrect. Rejecting it as invalid.
