Maintenance

[loleg]

It's been a while since this repository has seen any updates, and there are a number of critical issues.
This data package has value to the community, and overlaps somewhat with:

• https://github.com/OpendataCH/swiss-maps
• https://opendata.swiss/de/dataset/swisstlmregio-names
• https://osmnames.org/

I'll create a community fork @OpendataCH to see if anyone is interested to help maintain it.
