Add lamp type quest

[FloEdelmann]

Adds lamp_type to highway = street_lamp. I didn't suggest this quest in upstream StreetComplete because it probably does not pass the quest guidelines:

• 🚧 To be added tag is established and has a useful purpose
  • It is widely in use (> 1M)
  • There is a less popular but similar competing tag
  • It is used for rendering in https://sb12.github.io/OSMStreetLight/ (but that probably is not enough to be useful enough for upstream StreetComplete)
• 🤔 Any answer the user can give must have an equivalent tagging (Quest should not reappear to other users when solved by one)
  • Yes
• 🐿️ Easily answerable by any pedestrian from the outside but a survey is necessary
  • Not always easy to answer
  • Survey is necessary
• 💤 Not an overwhelming percentage of quests have the same answer (No spam)
  • Depends on the region
• 🕓 Applies to a reasonable number of map data (Worth the effort)
  • Yes, as there are more than 4M street lamps

But I wanted to use it anyway and thought, maybe it is good enough for inclusion in SCEE.

Without images hard to tag. But fine with me

Proabably ot easy to tell, but maybe it will encourage some users to become experts in lamp types?
