Sounds 1.0.0

This is a huge update! Thank you to all my Ko-Fi Supporters for helping me test out and recommend features.

New Additions

• Added support for 1.21!
• Added over 56 new block sounds - bringing Sounds' featureset inline with QualitySounds. These sounds are sourced from Zapsplat, a premium foley library.
• Added an incompatibility screen to tell players that Sounds and QualitySounds do the same thing, and that they will conflict.
• A cleaned up configuration screen, the ko-fi and discord grid widgets have been turned into buttons which lie next to the "Done" button.
• Ko-Fi supporters are given a "Thank You" in the config screen in the form of a little splash text.
• Cleaned up various implementations, hopefully reducing non-reproducible bugs in the future.
• Added new TagPair classes which can be used by mods to implement their own custom block sound configurations.

Fixes

• Fixed issue with enderpearls not having unique sounds when the toggle is enabled.
• Fixed compatibility issue with Inventorio, the "Item Drop" sound effect no longer is spammed when opening the inventory when inventorio is enabled.
• Fixed issue where the background of the config screen isn't rendered, which allows you to see the previous screen rendered underneath the config screen.
• Fixed crashes when a configured sound's sound event ID is not valid, you will now recieve a toast warning you that the sound is broken and that you should fix it!
• Fixed various mixin targets to be cleaner and require less modification across versions (specifically Leashes and cakes)
