Re-enable export plugin to remap Orchestrations to binary format

[Naros]

Describe the bug

In GH-693, the export plug-in was disabled due to an issue with translating .torch files to .os files.

The underlying problem is that Orchestrator relies on a post-initialize step that amends the loaded resource state with some transient state that influences specific behaviors for certain nodes. In the case of GH-693, this was the resolution of the _chainable member variable.

Since the export plugin does not perform this post-initialize step, transient state is missing when the exporter writes the binary data to the target remap file, and so some properties for nodes are not being correctly serialized. In the case of _chainable, this causes the binary remap file to mark the node as not-chained, and this causes the Orchestration to behave differently than what is observed in the editor.

Expected behavior

Additional information

We need to test and see what problems, if any, could result from performing the post-initialize step during the export plugin's stage where .torch files are converted to binary format. If there are issues, then we nee to re-evaluate transient state entirely.
