Wrapper around an AutoFile& that implements a ring buffer to deserialize from.
It guarantees the ability to rewind a given number of bytes.
Will automatically close the file when it goes out of scope if not null. If you need to close the file early, use file.fclose() instead of fclose(file).

Advance the stream's read pointer (m_read_pos) by up to 'length' bytes, filling the buffer from the file so that at least one byte is available.
Return a pointer to the available buffer data and the number of bytes (which may be less than the requested length) that may be accessed beginning at that pointer.
