Code packaging for script tasks

[spitz-dan-l]

Currently script tasks cannot use code packaging. This would be useful for a variety of purposes, including running non-python code snippets that may import user-authored source code.

To do it, I think you'd need to render the code package extraction code as bash in the script wrapper. Any future changes to code packaging that affected extraction would have to be maintained in two places- the python version and bash version.

Is this something you'd be interested in accepting as a PR?
