mio::Coords take lat/lon over easting/northing
When both lat/lon and essting/northing are provided in a file, meteoio seems to take lat/lon and produce new correct easting/northing from that. The problem is that many error message in A3D or streamflow use CH1903 coordinate to indicate the cell, so the user might look to that instead of lat/lon which could lead to misunderstanding of the issue. My advice would be to throw an error if multiple coordinates are given (but at some time just giving easting-northing was not working, I do not know if it has been fixed), are at least to throw an when both are given but they do not match
