    - #### getCodec

          public static Codec getCodec(int value,
                                       InputStream in,
                                       Codec defaultCodec)
                                throws IOException,
                                       Pack200Exception

      Returns the codec specified by the given value byte and optional byte header. If the value is >= 116, then bytes may be consumed from the secondary input stream, which is taken to be the contents of the band_headers byte array. Since the values from this are consumed and not repeated, the input stream should be reused for subsequent encodings. This does not therefore close the input stream.
      Parameters:
        `value` - the canonical encoding value
        `in` - the input stream to read additional byte headers from
        `defaultCodec` - TODO
      Returns:
        the corresponding codec, or `null` if the default should be used
      Throws:
        `IOException` - if there is a problem reading from the input stream (which in reality, is never, since the band_headers are likely stored in a byte array and accessed via a ByteArrayInputStream. However, an EOFException could occur if things go wrong)
        `Pack200Exception` - TODO
