Parses a string with a GSE2 STA2 header line.

Official Definition:

However, many files in practice do not adhere to these defined fixed positions. Here are some real-world examples:

>>> l = "STA2           -999.0000 -999.00000              -.999 -.999"
>>> for k, v in sorted(parse_sta2(l).items()):              
...     print(k, v)
