HUGE thanks to Noobly Walker who practically carried most this update

Added:

• Added a bunch of famous moons and some dwarf planets (don't question how you're able to see them with just a spyglass)
• Added star spectral classes - Stars are now divided into distinct spectral classes (O, B, A, F, G, K, M) which dictate their size and brightness and are by default distributed based on real life (most stars are M-class), the distribution can be made uniform in the config
• Added multiple meteor shower colors
• Added a bunch of config settings for how stars appear

Changes:

• Stars now lose brightness with distance, giving a more 3D feel to the Milky Way galaxy
• Minimal distance at which Z sky axis is rotated by 90 degrees has been changed from 100 000 blocks to 10 000 blocks
• Year length is now configurable

Fixes:

• The Moon's phases should now properly line up with where it is in the sky

Added:

• Compatibility with Enhanced Celestials

Fixed:

• Supernova is no longer visible during the day before it has exploded

Added:

• Io, Europa and Callisto are now orbiting Jupiter

Fixed:

• Potential crashes related to sky event rarity

Added:

• Orbiting objects (Planets and moons can be seen in the night sky orbiting around each other)

Fixes and changes:

• Rewrote the entirety of rendering code to make usage easier
• Star size now changes with distance

Removed:

• Alpha, Beta and Gamma effects (there are plans to replace those with a better, more flexible system)

Added:

• Supernovae
• Shooting Stars
• Meteor Showers
• 3 new configurable sky effects ("stellarview:alpha_effects", "stellarview:beta_effects" and "stellarview:gamma_effects"; must be added to the "effects" field of the dimension_type to work)

Fixes and changes:

• Fixed insufficient memory crash (Sorry about that, I turns out I missed fixing it in the 1.20.1 version, all the other versions are fine though)
• Increased the max configurable distance for the Galaxy
• The Moon now blends with the sky during day

Added:

• Supernovae
• Shooting Stars
• Meteor Showers
