Support for SPICE C-Kernels: data type 1

[ChristopherRabotin]

High level description

NASA provides plenty of CK files for its various missions, and mission stakeholders might request attitude files in that format.

Requirements

• Read C kernels of data type 1: https://naif.jpl.nasa.gov/pub/naif/toolkit_docs/C/req/ck.html#Data%20Type%201
• Write C kernels of data type 1 from a list of provided Quaternions and Rates: consider an AttitudeRecord structure similar to the EphemerisRecord used for building ephemeris files.

Test plans

• Find a public CK file, validate the reading and interpolation with the equivalent SPICE call.

Design

Start by building a new NAIF structure to store these files in the Almanac. If it isn't a DAF, then the CK structure will vary quite a bit; but if it is, then mimic the SPK and BPC handling.
