rclone serve webdav implements a basic webdav server to serve the
remote over HTTP via the webdav protocol. This can be viewed with a
webdav client or you can make a remote of type webdav to read and
write it.
NB at the moment each directory listing reads the start of each file
which is undesirable: see https://github.com/golang/go/issues/22577
