A lot of the helpers in `helpers.ts` are heavily bound to NodeJS and at the moment we're trying to make the `Connection` class be able to run in multiple environments. Its only remaining Node dependency was its reliance on `helpers.ts`, which it only needed for `assert`. This is a useful change also because `helpers.ts` is quite large and full of functions that do different things; I think we can name them better and move them into modules with a specific purpose rather than a generic `"helpers"` dumping ground. Once this change lands `Connection` should be usable in the browser.
