Support CfxLua

[mdxwzl]

• Implemented CFX Lua as a feature flag - cfxlua
  • Compound Operators: +=, -=, *=, /=, <<=, >>=, &=, |=, and ^=
  • Safe Navigation e.g. t?.x?.y == nil
  • In Unpacking e.g. local a, b, c = t is equivalent to local a, b, c = t.a, t.b, t.c
  • Set Constructors e.g. t = { .x, .y } is equivalent to t = { x = true, y = true }
  • C-Style Comments (single & multiline) e.g. /* comment */
  • Compile Time Jenkins' Hashes e.g. `Hello, World!` -> 1395890823

Would be glad if someone can look over it. I tested the workflows locally with Docker, and it keeps changing up the bytes, line & character values in the AST. Somehow, they are not the same in the workflow environment as on my Windows machine.
