For every FIFF_DATA_BUFFER tag in a continuous recording FiffStream builds one FiffRawDir entry: the kind of buffer (int16 packed, float32, ...), the first sample index of the buffer in the recording's sample timeline, the number of samples it contains, and the on-disk byte position of the underlying tag header. Together those entries form the sample → file-position index that FiffRawData::read_segment uses for random-access decoding.
