/*  Using the WebDAV server

    From windows file explorer,
        \\ESPWebDAV.local\
        or http://ESPWebDAV.local/
        or Map Network Drive -> Connect to http://ESPWebDAV.local/
           subst w: \\ESPWebDAV.local/DavWWWRoot
    From macOS Finder > command-K > http://ESPWebDAV.local/
        (do not select anonymous to have write access)
    From macOS cmdline:
        mkdir -p /tmp/esp; mount_webdav -S -i -v esp8266 http://ESPWebDAV.local/ /tmp/esp && echo OK
    From linux:
        use mount -t davs2 http://ESPWebDAV.local/ /mnt/
        use gio/gvfs/nautilus/YourFileExplorer http://ESPWebDAV.local/

    When running emulation on host (script ./run), use one of these URLs instead:
