idf converted to epjson alphabetizes by object name

[joseph-robertson]

Issue overview

This causes, for example, output tables to have different order of rows.

IDF

epJSON

We could use nlohmann::ordered_json instead of nlohmann::json, which would preserve the insertion order of object keys. There may be a slight performance hit, so we'd probably want to make the ordered version optional.

@joseph-robertson I don't think this is a defect. JSON objects are by definition unordered (see https://www.json.org/json-en.html), so we shouldn't be adding significance to the ordering this way, particularly for the sake of the HTML tables.

[joseph-robertson]

Perhaps instead of an approach like #11480, we think about sorting rows of the output tables (and other outputs). Maybe introduce a new object, something like OutputControls:OutputSorted (default=No). Could affect CSVs, tables, anything sortable (not, e.g., EIO).
