I was considering creating a constant of this to support quickly changing this to 512 in the future, something like:

const SRI_ENCODING = "sha256"; // near the top

// ... code
                algorithms: [ SRI_ENCODING ],

Thoughts?

Note, I registered this as such because sri:generate will fail without this step.
