Could use some polish, but with this, after
```nu
use .../task.nu
```
the command `task` exists and will output this
```console
$ task

Since 0.101.0 we will finally catch more illegal `def` signatures. As
the grammar for input/output types is rather restricted, this would
error otherwise
Also renamed the module to task instead of job,
https://www.nushell.sh/book/background_task.html will need updating.
Other than that, this should work.
