Update ClimateDataCell lon values sent in API responses to 4326

[CloudNiner]

Currently we respond with ClimateDataCell lat/lon in our Indicator, climate data and City endpoints. We should consistently respond with geojson point features in EPSG4326. That's currently not the case, because our lat lon values are pass through from the internal netcdf value where lon is [0 - 360). We can still provide the original netcdf lat lon values as geojson properties if desired.

This would be a breaking change for users depending on this data.
