Demo workflow and notebook: Al R-values

[Gbowker]

Demo which runs tensile simulations at 0, 45 and 90 to cube texture.

• Notebook which plots the data.

• Remove resources to make machine-agnostic
• Add demo to manifest so it can be run from CLI.

Largely looks fine to me, though I emphasise that I'm no expert on the scientific content.

Definitely minor point

I think things like:

Path(f"{workflow_path}/execute/t_1/e_0/pole_figure.png")

can instead (because workflow_path is already a Path) be written as:

workflow_path / "execute/t_1/e_0/pole_figure.png"

I believe that those two are equivalent.

I would not regard that as a reason to reject a PR.

Thanks @dkfellows ! Any review is a good review!
I acknowledge that this requires several improvements in the notebook to make it more streamlined and easy to understand as a demo and am happy to make any changes like this to do so.

Code looks acceptable. I don't know the science to tell for sure, but there's nothing in there that looks wildly off.

Looks good @Gbowker. In the notebook, would you be able to add a link to the demo workflow template on the docs site that you used to generate the workflow (in the format https://docs.matflow.io/stable/reference/workflows.html#tension-damask-al, where you modify tension-damask-al)? And a couple of sentences on what the R-values should look like for the different loading directions? Thanks!
