CCSDS 502.0-B Orbit Parameter Message parser and serializer
opm: redo interop — Orekit computes Keplerian→Cartesian, writes OPM
Replace hand-crafted KVN echo-through with genuine oracle work:
Orekit converts Keplerian orbital elements to Cartesian state vectors
(LEO, GEO, SSO, HEO, equatorial), writes OPM KVN. Our parser reads
Orekit's output and verifies metadata + state vectors match.
