+Simple atomic FIFO for passing data between threads or processes.
+This does not require mutexes.
+
+One thread modifies the readCounter and the other thread modifies the writeCounter.
+
+TODO The internal low-level implementation might be merged in some form with audio_utils fifo
+and/or FMQ [after confirming that requirements are met].
+The higher-levels parts related to Oboe use of the FIFO such as API, fds, relative
+location of indices and data buffer, mapping, allocation of memmory will probably be kept as-is.
