datenanfragen-bot and US address suggestions

[fm]

datenanfragen-bot is suggesting the state + zip be on a separate line from the city, but #975 says City, State, ZIP should be on the same line (country of course goes on its own line)

The check is currently simply replacing commas with newlines if there are too few of the latter:

data/src/checks/record/address-newlines.ts

Line 13 in 54f4787

suggestions: json['address'].includes(',') && [json['address'].replace(/\s*,\s*/g, '\n')],

We already have specific address processing for Germany. We'll need to also add that for the US (and other countries).
