+The read callback should return MA_SUCCESS if more than zero bytes were successfully read. If zero
+bytes can be read because it reached the end of the file, return MA_AT_END. If any other error

+actually read is less than the number of bytes requested (bytesToRead), miniaudio will treat it as
+if the end of the file has been reached and it will stop decoding. This becomes relevant for things
+like streaming data sources, such as internet streams. If you haven't yet received `bytesToRead`
+from the network, you need to have your callback wait for it and then only return when the full
+number of bytes can be output, or when you've reached the genuine end of the stream.
