/**
 * A deterministic JSON stringify implementation. Heavily adapted from https://github.com/epoberezkin/fast-json-stable-stringify.
 * This is needed because insertion order for JSON.stringify(object) affects output:
 * JSON.stringify({a: 1, b: 2})
 *      "{"a":1,"b":2}"
 * JSON.stringify({b: 2, a: 1})
 *      "{"b":2,"a":1}"
 * @param data Data to be JSON-stringified.
 * @returns JSON.stringified value with consistent ordering of keys.
