Starflight Innovation

* Sky rendering changes for better compatibility with shaders. * The small base structure now generates with ancient humanoid mobs. * Underground lakes on Mars now generate with an ice cover.

- Added the planets Mercury and Venus. - Added a few new mobs. - Added new structures on other planets. - Added Volcano structures containing more dense mineral resources that can also be found on Earth. - Added a new vehicle type, the airship. The main reason was flight between the surface and sky dimensions of Venus. - Added the targeting computer and targeting card for automatically landing rockets at specific coordinates. Shift right click a targeting card on the block at the center of the landing zone and then right click a targeting computer to insert. - Reworked the tech tree of machines. - Improvements to rocket control and flight mechanics. - More robust method of loading data pack planets behind the scenes. - Overall a massive update to functionality. Documentation is being written for the GitHub Wiki page: https://github.com/nanorover59/Starflight-Innovation/wiki

- Now available on Modrinth! - Full multiplayer compatibility. Fixed several issues with planet objects and retrieval of their data that were in the way of this. - It is now impossible to get stuck in a respawn loop from falling into the void.
