Function Compiler

Adds commands:

• data modify storage <storage> <path> set value <value>
• execute store result storage <storage> <path> int 1
• function (with argument support)

Adds selectors: @p, @r

Adds selector argument: sort

Adds nbt support internally

Adds nbt paths: foo.bar, foo[0]

Adds a better instruction optimizer

Functions compile in the background now

Fixes bugs:

• @e returned dead players
• Commands which remove entities from the world broke selectors
• execute align does not work
• Using /function in non-compiled functions does not run the compiled variant (affects 1.20.4+)
