Adding shop=tyres rendering

[kocio-pl]

Related to #2619

shop=tyres is the last of very popular shop types - above 10k uses - which have no special icon (the other one is shop=boutique, but it was rejected 2 years ago). This icon was designed by @MaestroGlanz and I find it good enough for this style:

Any comments/reviews about it?

I cleaned the icon a bit and made it 12px tall to leave 1 px margin in a 14 px icon. Was that the way the other icons were sized?? It seems very tiny... https://gist.github.com/daganzdaanda/d0e644e0fa1844597f800d0aedddc372

It kind of looks like there's a perspective to the icon, although that could also be a tyre on the left and a rim on the right.

@daganzdaanda No, most of the icons are using 14px matrix, so you don't have to resize it.

At 14px original proposition (1) looks more readable for me than the new one (2), so I left this code unchanged:

1. 
2. 

I think in this case it's hard to avoid perspective at all. We've used it also for optic and book icon for the same reason.

I have trouble deciding about merging this code. "A pull request should have at least one review before it is merged" (#2436 (comment)) - but do we need formal review (like this one) or any comment indicating that other developer have seen it (like this)?

The problem is lack of review or reaction is common situation with our PRs, so decision making process is still not quite effective.

For me this means a formal review.

I prefer the second icon shown, as I find it just as clear, and fits with our style guidelines.

[kocio-pl]

I doubt there's any difference in how both of them apply style guidelines, but reworked icon is also acceptable for me:
