feat(protocol-designer): wire up staging areas to loadFixture commands

[jerader]

closes RAUT-744 RAUT-770

Overview

Wires up the staging areas to create loadFixture commands and when you import a protocol back to PD, the loadFixture commands get populated back as staging areas in redux

Test Plan

Make sure the deck configuration ff is turned on and add a staging area in the create file wizard. Export the protocol. Open the json file and see that there is a loadFixture command associated with the staging area and location that you added.

Change the version in the json file from 7.0.0-candidate-d to 7.1 so the protocol doesn't unnecessarily go through a migration. Then import the protocol back into PD. Open dev tools and look at StepForms -> additionalEquipmentInvariantProperties and see that the staging area entities are there.

Changelog

• add logic for import/export to manage the staging areas
• fix the import order on the files
