    Allow compiling opus without the Makefile downloading it
    
    If you want to stuff SNIS into a flatpak, you can't have it use wget
    from the Makefile.  It uses wget to get the opus speech compression/
    decompression library from mozilla.org by default.  This patch allows
    you to pre-download this library then use it from the pre-downloaded
    location instead of using wget by, e.g.:
    
        make PREFETCHED_OPUS=../../opus-1.3.1.tar.gz
