[Tagging] River crossing grade

[Timothy Noname]

I think depth and width are too difficult for the average mapper to
determine and would be difficult for users to interpret.

I agree that some sort of tag is needed to describe the ease of crossing.
I see fords on OSM footpaths all the time and have no idea if they are a
potential obstacle or not. Most of them are very easy to just step over,
some require waterproof boots, some the water might come up to your knees.
Some are also tidal and the variance is huge.


I would suggest some possible values:
step_over, very_shallow (trainers ok), shallow (waterproof boots needed),
wade, swim, difficult_swim

Tag name something like
foot_crossing_grade
foot_crossing_grade:min
foot_crossing_grade:max
