WIP: feature: Add tle-plot

[kerel-fs]

Example: space tle plot norad=44832 norad=44831 norad=44830 norad=44829 norad=44828 norad=4482

todo.

• Find a proper name
• Add more parameters:
  • ecc, sma, incl, raan
  • arg of latitude (in seconds, i.e. folded with the period/360°) or similar
  • advanced: add option to propagate the orbits, show osculting elements?
• Investigate possible re-use of parts from space.map

Hello, and thank you again !
I made something similar to this in a private repository, but wanted to go a bit further by making it compatible with plotting the same parameters with an ephemeris file. Thus the idea to make it a completely independent command (lazily called history). It works with osculating elements, but features a very crude running mean, can display altitude, apogee, perigee, eccentricity, Local Time at Ascending Node (useful for sun-synchronous satellites), and Longitude (for GEO).

It's still rough around the edges, but I planned on putting it in the space-command package. Maybe I should put it in a branch here. What do you think ?
