community choser pins not accurately placed on seed location

[brenzi]

Gesell has a community with one location:

~/encointer-client-notee list-locations --cid u0qj95PYNyD
listing locations for cid u0qj95PYNyD
lat: 47.3895147567476087147 lon: 8.5170140862464904785

here's where that should be:

https://www.google.ch/maps/place/47%C2%B023'22.3%22N+8%C2%B031'01.3%22E/@47.3895148,8.5148254,17z/data=!3m1!4b1!4m5!3m4!1s0x0:0xee1e99f8f6bccbaa!8m2!3d47.3895148!4d8.5170141

But the app shows it rather here:
https://www.google.ch/maps/place/47%C2%B023'22.3%22N+8%C2%B031'01.3%22E/@47.3950364,8.5034611,20.75z/data=!4m5!3m4!1s0x0:0xee1e99f8f6bccbaa!8m2!3d47.3895148!4d8.5170141

@clangenb could this be conversion errors? encointer/encointer-js#35

Hmm, this would surprise me. If we look at the numbers:

47.3895148 8.5148254,17 vs:
47.3950364 8.5034611,20.75

This should be too much of a difference for just a floating-point discrepancy

[brenzi]

this is caused by the fact that we derive the location from the cid geohash, which would be good enough (as it points to Zurich)

So this is actually a wontfix. We'd better avoid too close communities
