SGP4 library for Go

Background

The C++ SGP4 library is ported from here

Initial port was done by sataas

How to update the bindings

You will need SWIG
Clone the original C++ SGP4 repository
Run: swig -c++ -intgosize 64 -go SGP4.i
The generated file will be cppsgp4/cppsgp4.go

TODO

Remove all unnecessary dependencies for testing
Enhance SGP4 Go API by adding more native C++ library functions
Enhance documentation
