The wasm codebase assumed that clients want to represent text as a string of characters. This is faster, but in order to enable backwards compatibility we add a `TextRepresentation` argument to `automerge_wasm::Automerge::new` to allow clients to choose between a `string` or `Array<any>` representation. The `automerge_wasm::Observer` will consult this setting to determine what kind of diffs to generate.
