/**
 * @name formatRFC3339
 * @category Common Helpers
 * @summary Format the date according to the RFC 3339 standard (https://tools.ietf.org/html/rfc3339#section-5.6).
 *
 * @description
 * Return the formatted date string in RFC 3339 format. Options may be passed to control the parts and notations of the date.
 *
 * @typeParam DateType - The `Date` type, the function operates on. Gets inferred from passed arguments. Allows to use extensions like [`UTCDate`](https://github.com/date-fns/utc).
 *
 * @param date - The original date
 * @param options - An object with options.
 *
 * @returns The formatted date string
 *
 * @throws `date` must not be Invalid Date
 *
 * @example
 * // Represent 18 September 2019 in RFC 3339 format:
 * formatRFC3339(new Date(2019, 8, 18, 19, 0, 52))
 * //=> '2019-09-18T19:00:52Z'
 *
 * @example
 * // Represent 18 September 2019 in RFC 3339 format, 3 digits of second fraction
 * formatRFC3339(new Date(2019, 8, 18, 19, 0, 52, 234), {
 *   fractionDigits: 3
 * })
 * //=> '2019-09-18T19:00:52.234Z'
