meteoIO writes out epsg code that it doesn't accept as input
Steps to reproduce the problem:
- Use for example data converter to create a smet file, without specifying epsg code in the source.
- The output file will contain ""epsg = -1""
- Reading the output file again by data converter produces an error message: ""[CoordsAlgorithms.cc:310] InvalidArgument: Invalid epsg code -1 (it should be between 0 and 32767)!""
In short: meteoIO can produce output that it doesn't accept as input!
