[talk-au] Adding lane tags to major roads

[Andrew Harvey]

I just checked again, it looks like you haven't corrected this yet, so a
friendly reminder it would be nice to have this fixed.
I think it's also a good idea to include the NSW LPI Imagery as the
default background layer for this task. I just filed
https://github.com/osmlab/maproulette3/issues/572 in relation to this.
