Provide a way to create DatePicker for Years with NxM grid for year values

[PoltP]

I'm creating a date picker for Years and our design contains 4x4 grid for year values, for sample:

2015  2016  2017  2018

2019  2020  2021  2022

2023  2024  2025  2026

2027  2028  2029  2030

Now, looks like there is no way to implement it using react-datepicker.

As you know, inside the '../src/date_utils.js':

export function getYearsPeriod(date) {
  const endPeriod = Math.ceil(getYear(date) / 12) * 12;
  const startPeriod = endPeriod - 11;
  return { startPeriod, endPeriod };
}

we see '12' as a number of years. Also, this number is used inside another related code (yearsDisabledBefore, yearsDisabledAfter etc.).

Could you implement a property to set number or grid dimensions NxM of year values to show (similar to showTwoColumnMonthYearPicker)?

I reviewed a code and it looks not so hard as hard for us to fix it on our side.
