Improve atmospheric density approximation

[gomezzz]

Feature

Desired behavior

Better drag approximation

What needs to be done

Change the approximation in the orbital propagator at https://github.com/FG-TUM/OrbitPropagator/

@darioizzo could you post the source you mentioned? :)

How it can be tested

Look at particle decays over a month or so.

From Dario: atmosphere.zip

Can be used with

import pickle as pkl
with open("atmosphere.pk", "rb") as file:
    altitude, density = pkl.load(file)

Altitude is in km, density in kg/m3 from the NRLMSISE-00 model queried at 0 longitude 0 latitude on 01/02/2021. Altitude in [78, 1000] km. density above 1000 can be considered as 0.

I think this can be closed? @FG-TUM
