Feature request: TLE support

[andresv]

Very nice library!

It would be awesome to see TLE support in this library so it can be used for tracking satellites.

Currently rust-gpredict can be used for that, however it relies on C libgpredict. It would be better to use rust native library.

Thanks!

And yes, extracting TLE data and applying SGP4/SDP4 models to it does sound like a great feature to add. I'll look forward to implementing it in pure Rust.
