 * Time warp CLI - thin wrapper around warp library

 *   npm run warp node [leadTime]   - Warp to next maneuver node (default 60s before)
 *   npm run warp soi [leadTime]    - Warp to next SOI change
 *   npm run warp periapsis         - Warp to periapsis
 *   npm run warp apoapsis          - Warp to apoapsis
 *   npm run warp <seconds>         - Warp forward by N seconds
