/**
 * Get timeslots from starting and ending time
 * @param  {string} startTime  -  start time in format "HH:mm"
 * @param  {string} endTime  -  end time in format "HH:mm"
 * @param  {number} timeInterval  -  time interval in minutes
 * @param  {boolean} formatRange  -  if true returns ranges like "10:00 - 11:00", if false returns single times like "10:00"
 * @param  {boolean} forceShowSeconds  -  Whether to force the display of seconds.
 *                                        By default, seconds are displayed only when the timeInterval is less than 1
 * @returns {string[]} Array of time slots
 * @example

console.log(getTimeslots("10:00", "14:00", 60, true)); //['10:00 - 11:00', '11:00 - 12:00', '12:00 - 13:00', '13:00 - 14:00']
console.log(getTimeslots("10:00", "14:00", 60));   // ['10:00', '11:00', '12:00', '13:00']
console.log(getTimeslots("10:00", "14:00", 60, false, true));   // ['10:00:00', '11:00:00', '12:00:00', '13:00:00', '14:00:00']
console.log(getTimeslots("10:00", "10:07", 1.188118811881188));   // ['10:00', '10:01', '10:02', '10:03', '10:04', '10:05']
console.log(getTimeslots("08:00:00", "08:02:00", 0.4));   // ['08:00:00', '08:00:24', '08:00:48', '08:01:12', '08:01:36', '08:02:00']
