Handle living_street=yes

[Phyks]

See https://wiki.openstreetmap.org/wiki/Key:living_street

An highway=secondary + living_street=yes should be considered as an highway=living_street, probably with a slight penalty compared to the latter one.

[althio]

Maybe something should be kept similar to highway=secondary rendering (eg. 'secondary' casing).

«It is supposed to mark a road that has a different classification than 'living street' but is a living street.»
living_street=yes is a something different than a proper living street, so I think we should not trust this tag alone to know if a street is quiet or not.

It seems to be used a lot in Russia for roads next to high-rise block (tagged as service + living_street=yes)

living_street=yes is deprecated as per the wiki and rejected on the main osm.org render.

I'll close this issue for the moment as not relevant directly for CyclOSM render then. It might still be a really useful feature (I think so, at least), so we should probably try to resubmit it to tagging ML?
