[Tagging] Status of oneway=cw oneway=ccw

direction=clockwise/anticlockwise makes sense for a node (like a
miniroundabout), not for a way

on a way, the common usage is "oneway=yes" and make sure the way (which is
by nature directional) is pointing the right direction.

It doesn't make much sense for a hiking route to use "clockwise" (why the
"cw" abbreviation???) or "anticlockwise" ("ccw" is presumably an
abbreviation for the American English word "counterclockwise"). Because
those terms only make sense if the route is a closed loop that doesn't
self-intersect, have branches, or anything complicated.

So "oneway=yes" solves all these cases quite simply. Avoid "oneway=-1" by
the way, just use "oneway=yes" and reverse the direction of the way if it's

My two cents (from extensive work on bus routes, not hiking routes).
