tiny_psnr: Support large files
...
If an input file is bigger than 2GB (assume sizeof(int) == 4)),
size0/size1 will overflow, making stddev and PSNR invalid.

tiny_psnr: fix range calculation for sample size of 32 bits
...
For a sample size of 32 bits, the shift would overflow producing
undefined results. Incidentally, in the only test currently using
32-bit samples, the output matches the reference exactly on most
systems meaning the bad 'max' value is never used.

tiny_psnr: skip wav headers on input files
...
The byte count printed excludes the header, and offsets are applied
after the the headers are skipped.
Reference files updated to reflect new output. Some stddev/psnr values
have changed slightly due to headers no longer being compared.
