feat: export and render building:part
First of all, thanks for this great project!
With this PR, I add the ability to export and render building:part relations (thanks to Multipolygon relations are supported natively by tilemaker).
For the 3D building render style, credits to @tgdbepe4 and his great style!
Resolve #458.
The result is shown below for 2 monuments in Rome (Italy).
| Building | Before PR | After PR |
|---|---|---|
| "name:it": "Castel Sant'Angelo" | ||
| "name:it": "Piazza San Pietro" |
OpenMapTiles says it just uses building=*, but later on goes to talk about the height of the building or building:part. I assume it's contradicting itself and in practice and the most common implementation includes building:part?
Thanks a lot for your work @c84c ! Taken as-is, it's going to bring some nice 3D buildings to cartes.app.

Hi Thanks for the work !
cartes.app users noticed an issue with this PR. It is discussed here in French.
It is coming from this recommandation in the wiki:
Where a building has been split into parts, a building outline has still to be drawn of the whole building way and should have the tags building:levels=* and height=*. These values should be the maximum of all the building parts.
Therefore the building outline way/90195611 "hide" the building:part(s) because it is higher.

The model in OSM is fine : https://beakerboy.github.io/OSMBuilding/?id=901956113
@c84c How can we modify the code to identify the building outline and set its height at 0 ? (we don't want to remove it since tags are on it)
