Add man_made features

[nvkelso]

The following are features which probably get included in buildings or landuse now, but we're not including many nodes (should be added to pois layer).

When it is in building layer, we should prefer the man_made=* value for the kind (over building=*).

Format is:
LINK to osm wiki, EXAMPLE to construct test, recommended MIN_ZOOM value, and COUNT of features.

• man_made=communications_tower, example - pois, zoom 14. Around 3500 pois, 185 buildings (make sure man_made value is used over building value).
• man_made=observatory, example - pois, zoom 13. Around 200 pois, 180 buildings (make sure man_made value is used over building value).
• man_made=offshore_platform, example, and another in Europe where they are more common - pois, zoom 12. Around 290 pois, 40 landuse/building (man_made=offshore_platform), ignore.
• man_made=silo, example - pois, zoom 16. Around 6800 pois, 40000 buildings.
• man_made=telescope, example - pois, zoom 14. Around 700 pois, 400 buildings/landuse (ignore).
• man_made=water_tower, example - pois, zoom 15. Around 40,000 pois, 15,000 buildings (ignore).

When there's a building polygon, we should put that in the buildings layer. If it also has POI tags, those get lifted off and added as a centroid in the pois layer. That logic should not change - this is just adding some new man_made types. Please do not change the existing POI / building logic.

Sounds good, thanks for clarification.

Skip silos, those are almost all buildings, and the shape alone should suffice.

(Adjusted a few of the zooms after validating with more test data.)

Looking good.
