Example of reading a Processing object from json

[kkappler]

With the new processing configs I am testing the functionality of writing to json (works fine) and reading from json (not working).

I created an outline of a test for this on branch dev in
aurora/test_utils/synthetic/make_processing_configs_new.py

The test is called test_to_from_json()

The output json is created, and it is read-in but something happens on line 659 of mt_metadata/mt_metadata/base/metadata.py on the call to self.from_dict(json_dict) .. maybe too many layers of nested dicts? The error message is pasted below

Traceback (most recent call last):

Configs are currently being saved during several of the synthetic tests.

• Add a line to the synthetic tests that confirms we can read in the config
• Confirm the ingested config can be used successfully for processing
• remove test_to_from_json() from make_processing_configs.py

We can test
