Atlas77 Compiler

This is the compiler for the atlas77 language. Here's a list of all the modules in the compiler:

• atlas_asm: The assembler for the atlas77 language it takes in a list of Instructions and outputs a list of bytes.
• atlas_codegen: The code generator for the atlas77 language. It takes in the Hir and outputs a list of instructions.
• atlas_frontend: The frontend for the atlas77 language. It takes in a string and outputs the AST.
• atlas_hir: The high-level intermediate representation for the atlas77 language. It takes in the AST and outputs the HIR. It also performs type checking, dead code elimination (WIP), and constant folding (WIP).
• atlas_macro: Utilities macros for the atlas77 language.
