Passing a diff directly rather than two files

[pawamoy]

Hey Will 👋 Very cool widget for Textual!

I was wondering how much effort it would be to support passing diffs directly to this widget, rather than two files. In short, I'm computing diffs myself, so I got a string like the following that I would like to pass to the widget:

--- a/docs/examples/workflows/upstream/scripts_python.md

 This example is a replication of an Argo Workflow example in Hera.
 The upstream example can be [found here](https://github.com/argoproj/argo-workflows/blob/main/examples/scripts-python.yaml).

If that's too complicated a feature, don't worry I can probably refactor my algorithm to avoid pre-computing diffs and do things on-the-fly.
