Compatibility update
- ANAIS is now fully compatible with SFS 1.6 (fixes the velocity arrow)
- Rewrote the orbit rendering algorithm - should now work with VerdiX optimization mod
- Moved the icon to my personal github repository since imgur is apparently banned for some countries (credits to @RoshanGamer7791 for the initial fix)
- Rewrote the Lambert solver for optimization and multi-turn management (unused for now - this is for a later version!)
