 * @brief     SBC decoder decode one frame
 *
 * This API decode one frame by sbc decoder.

 *
 * @param
 *    - sbc: sbc decoder context pointer;
 *    - data: buffer to be decoded;
 *    - length: the length of input buffer;
 *
 *
 * Usage example:
 *
 *    sbcdecodercontext_t sbc_decoder;
 *	  bk_sbc_decoder_frame_decode(&sbc_decoder, sbc_data, 512);
 *
 *
 * @return
 *    - consumed: buffer length by decoder if no error ocurs, else error code (always small than 0) will be return.
 *
 * @attention 1. the output PCM data please refer to the follows variables:
 *    - sbc->pcm_sample: means output PCM data address
 *    - sbc->pcm_length: means output PCM data length in sample
 *    - sbc->channel_number: means output PCM data channels
