What is the current behavior?

Issue Number: N/A

NOTE: Describe the current behavior that you are modifying, or link to a relevant issue.

When using the node.image program, the crossOrigin attribute is hardcoded to "" (anonymous fetch). If the img resource requires credentials, then image requests will always fail with HTTP 401, and the requested images will never be rendered on nodes.

What is the new behavior?

NOTE: Describe the behavior or changes that are being added by this PR.

Builds on PR #1147, where rather than hardcoding the crossOrigin attribute, the caller can provide a param value. Param value must be a valid HTML img crossOrigin value (TS check only). No breaking change in behavior - new params arg is optional. Also, FWIW, I've added a null param value which allows a user to override the behavior from PR #1147 and not specify a crossOrigin attribute.

This change specifically supports the (my) use case where node image URL resources are protected by a layer of authentication.
