Render parcel lockers

[ZeLonewolf]

Tagging for parcel lockers was approved in a 2021 proposal and has over 13,000 usages and growing as of the writing of this ticket. While this feature is only sparsely mapped in the US, these do exist here and we can expect them to grow over time.

Support for parcel lockers was proposed in gravitystorm/openstreetmap-carto#4512, but the maintainer team as of this writing has been unable to come to a consensus on rendering it. The render samples on that ticket can be used for inspiration as to how to draw them. As a regional style, I believe that we have the ability to be more forward-leaning when it comes to adopting new tagging that has clear community support but for which usage has only started to proliferate.

We do not currently have support for parcel lockers in the vector tiles. This will either need to be added to OpenMapTiles, which is proposed in openmaptiles/openmaptiles#1390, or created in a custom layer, which requires onthegomap/planetiler#160.

Unlike many other POI types, we’re probably unlikely to find examples of parcel lockers in existing print maps to use as a guide, since they’re a fairly recent innovation.

#128 tracks POI icons in general. It would be useful to come up with a color system for POIs, like most maps have, which will streamline the addition of POI types in the future. That doesn’t necessarily block the addition of parcel lockers in the meantime – in fact, we could even stick to black silhouettes for now for simplicity, along the lines of a Rand McNally or NPS map.
