Set the audio format support of a mpg123_handle in detail:
* \param mh handle
* \param rate The sample rate value (in Hertz).
* \param channels A combination of MPG123_STEREO and MPG123_MONO.
* \param encodings A combination of accepted encodings for rate and channels, p.ex MPG123_ENC_SIGNED16 | MPG123_ENC_ULAW_8 (or 0 for no support). Please note that some encodings may not be supported in the library build and thus will be ignored here.
* \return MPG123_OK on success, MPG123_ERR if there was an error.
