[Tagging] Finger- or guide-post text

[Andy Mabbett]

I am mapping a fingerpost, aka guidepost:

   https://wiki.openstreetmap.org/wiki/Tag:information%3Dguidepost

I would like to add the inscription, for each of the three fingers,
with their compass points. I note:

   https://wiki.openstreetmap.org/wiki/Key:destination

is similar but "destination:forward" and "destination:backward" are
meaningless in this context; and many finger posts have more than four
fingers, or fingers not at 90-degree angles to each other, or to
North. I propose something like:

   destination:NNW=foo

or, using degrees:

   destination:337.5:=foo

If this would cloud the use of "destination", we could use, say:

   inscription:337.5:=foo

What do folk think?
