Convert SPICe trajectory date into Chebyshev polynomials

[joaogvcarneiro]

Describe your use case
One way to condense position and velocity data is to parameterize them into orbital elements represented by Chebyshev polynomials. The spacecraft can then take the corresponding coefficients and turn them back into the ephemeris data.

Describe alternatives solutions you've considered
N/A.

Additional context
The second piece to this is the FSW module that converts the Chebyshev coefficient data back into usable position and velocity arrays.
