* @description
* Return the array of quarters 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
*
* @returns The array with starts of quarters from the quarter of the interval start to the quarter of the interval end
*
* @example
* // Each quarter within interval 6 February 2014 - 10 August 2014:
* const result = eachQuarterOfInterval({
* start: new Date(2014, 1, 6),
