- having "image" visible when the "wikimedia_commons" from moreFields is shown looks wrong, so now both are optional
- reorder fields

Following openstreetmap#964 (review)

- rename file to follow convention that locationSets should be part of the filename
- add Q46 which represents europe

Code via https://location-conflation.com/?locationSet=%7B%20include%3A%20%5B%27q46%27%5D%20%7D%0A

- remove "addr:" field since small usage and discouraged
- add addr_string which is the thing used most often
- update addr_addr to only show if at least "memorial:addr:street" is present

The `prerequisiteTag` did work nicely. However, the `"type": "address"` only allows to set `addr:*` keys, so we cannot re used it as is. Removing it for now…
