Vincent Ambo 127ef98486 refactor(tazjin/rlox): Represent VM values as enums
Introduces a new enum which represents the different types of possible
values, and modifies the rest of the existing code to wrap/unwrap
these enum variants correctly.

Notably in the vm module, a new macro has been introduced that makes
it possible to encode a type expectation and return a runtime error in
case of a type mismatch.

This is an interpreter for the Lox language, based on the book "Crafting Interpreters".

The book's original code uses Java, but I don't want to use Java, so I've decided to take on the extra complexity of porting it to Rust.

Note: This implements the first of two Lox interpreters.
