    Filesystem driver: add chunk size config option

    At the moment, the filesystem driver uses a hardcoded 64 KB chunk
    size, used when reading/writing image files.

    This can be extremely inefficient, especially when file shares are
    used.

    For this reason, this change will make it configurable.
