avcodec_decode_audio4 is deprecated in favor of send_packet(), send_eof() and receive_frame() #141
Description
I was just looking at switching from rust-ffmpeg-next back to this project but realised one of the changes I'd miss is the addition of these send_packet(), send_eof() and receive_frame() functions for the Opened struct.
It would be great if something like this could be cherry picked...
