Add Bicycle Parking Data Set (FixMyBerlin/atlas-geo#70)

This PR adds two data sets containing entries of bicycle parking
infrastructure. One contains point geometries of bicycle parking and the
other contains mostly parking areas which are mapped as areas. The point
data set also includes the entries of the second data set where the
respective point corresponds to the centroid of the mapped area.

Capacity values get processed s.t. the `capacity` tag only contains the
number of "normal" bicycle parking spots and not the total parking spots
e.g. `capacity = capacity - capacity:cargo_bikes`. Apart from that we
copy only the tags described on the [OSM Wiki - Bicycle
Parking](https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dbicycle_parking)
page.
