refactor(tazjin/rlox): Thread lifetimes through interpreter r/2104
In order to store a function in the interpreter's representation of a
callable, the lifetimes used throughout rlox need to be threaded
through properly.

This is currently not optimal, for two reasons:

* following the design of the book's scanner, the source code slice
  needs to still be available at runtime. Rust makes this explicit,
  but it seems unnecessary.

* the interpreter's lifetime is now bounded to be smaller than the
  source's, which means that the REPL no longer persists state between
  evaluations

Both of these can be fixed eventually by diverging the scanner from
the book slightly, but right now that's not my priority.
