.net Standard port of CUETools.Codecs.FLAKE Original code from Gregory S. Chudov and Justin Ruggles

This is for encoding into FLAC.

This has not been tested much yet, I just converted it to .net standard and left much of the original code intact

public void ConvertToFlac(Stream sourceStream, Stream destinationStream)
{
    using (var audioSource = new WAVReader(null, sourceStream))
    {
        var buff = new AudioBuffer(audioSource, 0x10000);
        using (var flakeWriter = new FlakeWriter(null, destinationStream, audioSource.PCM) { CompressionLevel = 8 })
            while (audioSource.Read(buff, -1) != 0)
            {
                flakeWriter.Write(buff);
            }
    }
}
