Migrate file-output from .pkl files to something else

The FEDS .pkl files cannot be read if generated using a different env. @eorland_gee and I confirmed this while scrambling to generate a record for Quebec, where I generated files from the ADE using the wrong env, and Eli was unable to read them.

@jsignell has been warning us about the dangers of using .pkl file for a while now. It does seem like we are one env-shift away from loosing the entire record. Moving forward, it makes sense to write out using a different file.

During the meeting @jsignell you said you would take a look at the code base and see if we could either shift to using only native-python objects in the .pkl files or looking at what files could be written out instead.
