Mechanical edit Proposal to clean up street=*-tag

[phodgkin]

@tekim

I agree that a MR challenge is a good place to start making fixes. Many of the examples I looked at had other issues, such as city=* when addr:city=* is probably correct.

Another point in favour of making all of cases 1-3 an MR challenge. Case 3 only adds 20% to the overall size of the task, so it would seem easier and safer all round to use MR.

You might want to exclude relations, or specifically associatedStreet (not worth the complication).
