Can markmeld "watch" my files?

The new [typst](https://github.com/typst/typst) `cli` has a cool feature where it will "watch" your files.

```bash
typst --watch main.typ

watching main.typ
writing to main.pdf

[12:58:41] compiled successfully
```

Something that would be awesome is if I could do a similar action with markmeld: `mm --watch pephub` and it will just listen for file changes and recompile my output.
