Largely untested!! Enables import_from_config to create a Pandas DataFrame from a list of dictionaries in a JSON file, in addition to rows in CSV and Excel files. To handle complex JSON files (where the root element isn’t just a list of the items/rows you want to import), we allow the config file to specify a jsonpath expression, which is used to identify the bit of the JSON object that we want to pull out. I wrote this code, hoping to import some data from a JSON file, but then realised the JSON file lacked constituency IDs, so would need to be geocoded first, making this change redundant (since whatever script does the geocoding could also output CSV instead of JSON). But maybe this code might be useful in future..?
