[Talk-GB] Standalone signalled pedestrian crossing tagging

[Edward Catmur]

Option 3 appears to be the only way to map an asl or to signify its (rather
their) absence. I don't think you can tag a combined (option 1) crossing
node with cycleway=asl.

It's also more consistent if nearby road junctions are mapped in detail for
standalone crossings to be mapped similarly.
