wavpack: updated to 5.8.0

5.8.0

Much of the development for this release stemmed from the discovery of \ 
situations where the quantization noise introduced with the hybrid mode was \ 
higher than expected, in particular with very low bitrates (e.g., < 3 bps) \ 
and high sample rates. This was traced to feedback in the decorrelation loop and \ 
has been addressed. Also, audio samples were discovered where the DNS (dynamic \ 
noise shaping) algorithm produced sub-optimal shaping, and this has been \ 
addressed with an all-new DNS algorithm. Finally, some issues were fixed that \ 
caused the "extra" mode performance to degrade with multithreading and \ 
also with the hybrid mode.

The other major change is that multithreading is now turned on by default for \ 
the command-line programs, assuming that a multicore CPU is detected. This can \ 
be disabled with a new option --no-threads.
