    /**
     * A byte window of a stored file, or null when the key is absent.
     *
     * `GETRANGE` slices server-side, so a window costs the window rather than
     * the whole value on the wire. Its bounds are inclusive and `-1` means the
     * last byte, which is how "to the end" is spelled.
     *
     * `EXISTS` rides along because `GETRANGE` answers an empty string for a
     * missing key, for an empty file and for a window past the end alike;
     * without it a read of a deleted path would return an empty buffer instead
     * of throwing. The two are issued together rather than through `MULTI`,
     * which drops the Buffer type mapping and hands back a lossy string:
     * node-redis pipelines commands issued in the same tick, so this is still
     * one round trip.
     *
     * @param path mount-relative path of the file
     * @param offset first byte to read
     * @param size how many bytes, or null for the rest
