Trustlang - Rust with effect system and more accessible macros

Trustlang compiler also wants to achieve those goals:

• Be fast
• Be compatible with a lot of architectures
• Be able to call C, C++, Rust and maybe some others code
• Be able to generate functions, compatible with C, C++, Rust and maybe some others

Stuff for developers:

Compilation Process (Version 3, October 19, 2023):

• Lexer, Tokens -> Language IR
• Type inference on Language IR
• borrow checking, Type checking & backend (backend is single for all crates) invocation (maybe I should move backend invokation out because of generic overduplication?)

Inside backend:

• [Probably, Hopefully] Backend is just a trait, so this should invoke the actual platfrom backend to [mostly] generate Backend IR (and variable metadate here too!)
• If backend uses IR, convert IR to machine code / [more likely] Invoke packager
• Packanger's job - package symbols (given - symbol name, some metadata and binary for the symbol), for example ELFs.

TODO and notes for development
