OSM: infer missing attributes

[namdre]

In some networks, roads that are split into multiple ways lack important attributes on some of these ways.

The latter way is missing the lanes attribute (presumably this slips through because it does not affect rendering style).
Such missing attributes are replaced by the default values and can create significant bottlenecks which invalidate a simulation.

It would be useful to identify ways that form a sequence (by topology and common street name?) and to infer the values of missing attributes from present attributes of surrounding ways.

As alternative, one could annotate objects so that the end use can easier find objects with guessed attributes and correct them manually (#16094)
