overlay : add parking_lane editing

[JLZIMMERMANN]

Use case
There is a great editor for parking_lane tag here.

Proposed Solution
The same as the overlay sidewalk for pedestrians an overlay would enhance a specific editing for cars.

Just wanted to open the same ticket :-).

We are working on collecting parking data for all of Berlin with a local community. And we are working on processing the OSM data to generate good parking data based on it as well. All this is WIP and documented at https://parkraum.osm-verkehrswende.org/. We use a modified version of the Zlant parking editor for this (Links below).

Based on this project, I have some input for the quest / overlay:

• It need to show separately mapped parking areas of type lane and street_side (and possibly surface for those cases that are miss-tagged). Otherwise we will generate bad data by mapping the parking data twice. The zlant-Editor does that by showing the separately mapped areas on the map.
  • Examples: https://tordans.github.io/parking-lanes/#20/52.47398/13.44293, https://tordans.github.io/parking-lanes/#20/52.47438/13.44614, https://tordans.github.io/parking-lanes/#19/52.47696/13.44571
• Right now, our project is focussed on just collecting "if and in which direction can be parked", eg parking:lane:left=parallel. To keep it simple, I suggest to focus on this, so the colors of the overlay could visualize "no parking:lane:<side> data" vs. "data present".
  • Side note: In the future, it would be gerat to be able to run the same quest for other sub-data like the parking-position (eg on_street), a simple condition check and mappging the surface below the cars (Topic of "Entsiegelung" (unsealing?))
