Function Compiler

Adds 1.21.2 and 1.21.3 support

Adds selector arguments: x, y, z

Fixes bugs:

• Compilation throws an exception due to using a library in which a function doesn't exist in older minecraft versions
• distance selector compares locations without checking if the entity is in the same world
• Attributes and effects don't work due to a cast error while loading (affects 1.20.5+)
• Entities using the same classes under the hood all match the [type] selector (those entities are not supported anymore, for now)
• Some macros throw an exception due to generating wrong bytecode
• Nbt compounds with a suffix as a value without quotes break parsing (b, d, f, l, s)
