* @name eachMinuteOfInterval
* @category Interval Helpers
* @summary Return the array of minutes within the specified time interval.
*
* @description
* Returns the array of minutes within the specified time interval.
*
* @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 interval - The interval.
* @param options - An object with options.
*
* @returns The array with starts of minutes from the minute of the interval start to the minute of the interval end
*
* @example
* // Each minute between 14 October 2020, 13:00 and 14 October 2020, 13:03
* const result = eachMinuteOfInterval({
* start: new Date(2014, 9, 14, 13),
* end: new Date(2014, 9, 14, 13, 3)
* })
