IONEX formatter
Data format to exchange ionospheric maps like on the Figure below:
Implements IONosphere map Exchange [format](https://files.igs.org/pub/data/format/ionex1.pdf) and writes data in corresponding format to a file. Each file could contain several maps, in general file contain maps for a single day. The file names also follows the file name convention cccedddh.yyI:
- ccc - 3 character analysis center designator
- e - extension for region code (G for Global Ionospheric Map)
- ddd - day of year of the first record (map) in a file
- h - file index (1, 2 ...) or hour (A, B ...) within a day. Letter are used
for hours since it need to fit one character. * yy - two last digits in year * I - file type (I for ionospheric maps)
Use cases
Currently CSV to IONEX format conversion is implemented. CSV data should have time, lattitude and longitude specification for each data point. Assume we have file data.csv with following content.
#year month day_of_month hour minute second lat lon val
