During conversion, if the user does not specify an output buffer or
specifies an output buffer that is smaller than what is needed, remaining
samples that are not written to the output are stored to an internal FIFO
buffer. This function can be used to read samples from that internal FIFO.
@param avr audio resample context
@param output output data pointers. May be NULL, in which case
nb_samples of data is discarded from output FIFO.
@param nb_samples number of samples to read from the FIFO
@return the number of samples written to output
Read samples from the output FIFO.
