Vincent Ambo 432e7a7ddd feat(tazjin/rlox): Intern all string constants 
This is again a step closer to the book, but there are some notable
differences:

* Only constants encountered by the compiler are interned, all other
  string operations (well, concatenation) happen with heap objects.

* OpReturn will always ensure that a returned string value is newly
  heap allocated and does not reference the interner.

README.md

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.
