    audio/lpcnet: New port: Neural Net speech coding
    
    Needed for freedv update see:
    https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=264769
    
    Experimental version of LPCNet that has been used to develop FreeDV 2020
    - a HF radio Digial Voice mode for over the air experimentation with
    Neural Net speech coding. Possibly the first use of Neural Net speech
    coding in real world operation.
