Add transfer of dicts.

[jgray-19]

Breaking change - Now it forces all tables to be references. So lists that were previously transferred need the .eval(), which does a shallow copy.

Updated documentation and examples.

Closes #20

Needs a release of MAD-NG to be merged.

Pull Request Overview

This PR implements a breaking change in the MAD-NG API to require that all table transfers be made by reference, with an option to perform a shallow copy using eval(), along with corresponding updates to documentation, examples, and workflows. Key changes include:

• Updating MAD-NG function calls (e.g. recv_vars, send) to include the new shallow_copy/true parameter.
• Renaming variables and updating file paths in examples to fix typos.
• Updating version numbers, changelogs, and workflow scripts to reflect the new MAD-NG release.
