Add roof shape orientation

[Coolawik]

Use case
We could tag buildings roof shape in app. Could you also add a choice of roof shape orientation for some of the selected roofs?

Proposed Solution
It could be useful for these chosen types of roofs:

1. gabled
2. hipped
3. half-hipped
4. round
5. gambrel
6. mansard
   and create tag roof:orientation="along" or "across"
