Audible fences should not be barriers

[tombay]

Investigating a routing issue I discovered that the node in question (431495501) was described thus: barrier=fence sensory=audio

(I have also seen sensory=audible)

In Australia we have audible fences that are used to prevent livestock (and wild dogs etc) from passing the barrier. These fences do not stop traffic (and are not meant to) as there is no physical fence. I question if these should be declared as barriers. The alternative would be to add the access=yes but that looks wrong to me. To reproduce use this example - the route along the Balonne Highway. https://map.project-osrm.org/?z=10&center=-27.957411%2C147.402191&loc=-27.965088%2C148.163815&loc=-27.993189%2C146.766357&hl=en&alt=0&srv=0
