Vincent Ambo ef7a0da8cb feat(tazjin/rlox): Add a simple string interner
This is based on this matklad post:

https://matklad.github.io/2020/03/22/fast-simple-rust-interner.html

It's modified slightly to provide a safer interface and slightly more
readable implementation:

* interned string IDs are wrapped in a newtype that is not publicly
  constructible

* unsafe block is reduced to only the small scope in which it is
  needed

* lookup lifetime is pinned explicitly to make the intent clearer when
  reading this code

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.
