GPS coordinates update

Via J. Heath:

Tirelli and Dana (are out of place on the website "villages" map. This is because of mistakes I made in the numbers on the GPS spreadsheet.

Corrected numbers:
Tirelli (Toro-So, Ter-So) north lat 14.38 / west long -3.34
Dana (Tommo So) north lat 14.66 / west long -3.27

I've uploaded updated GPS coordinates in simplified forms from Heath:

https://github.com/clld/dogonlanguages-data/blob/master/beta/deepblue_GPS.csv
https://github.com/clld/dogonlanguages-data/blob/master/beta/deepblue_GPS.xlsx

It looks like the data gets pulled in here from GPS_Dogon.csv:

https://github.com/clld/dogonlanguages/blob/2d897e2e5df1876f8c7bd32fabee9db65515dac1/dogonlanguages/scripts/util.py#L586

which actually has two fields with the same name for N Lat and W Lon.

I would suggest that we move over to the deepblue_GPS.csv simplified sheet (has only one set of coordinates and contains the other pertinent information (OfficialVillageName, Transcribed Village Name, social info) in a much less messy spreadsheet / CSV file.

deepblue_GPS.* is also archived permanently with DeepBlue.

If we switch, we can then delete:
