Add support for the polyglot steno keyboard

I bought a polyglot! I'm using embedded steno (so no plover for now) but
to use it with the WebHID interface I do still need to elevate my
permissions and put my keyboard into an editable state. This commit adds
udev support for using https://www.lim.au/#/software/javelin-steno to
edit keyboard options
