ea9982d9ea feat(tazjin/nittredir): Add Chrome extension to redirect to Nitter
There is another extension for this already, but it hooks in after the
page has already started loading - doing it on the URL change handler
is much faster.

5868d4bd49 refactor(tazjin/rlox): Prepare scanner for shared use
In the book, the clox interpreter has its own scanner which uses a
pull-based model for a single pass compiler.

I can't be bothered to write another scanner, or amend this one into
pull-mode to work with the treewalk interpreter, so instead I will
just reuse it and pull from a vector of tokens.

The tokens are shared between both interpreters and the scanner is not
what I'm interested in here.

fe97398fd9 refactor(tazjin/rlox): Thread lifetimes through interpreter
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.

* glittershark/home: Don't install rr, as it's not building with gcc10
