**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** `arrow-rs` does not support arithmetic between intervals, which does not allow full use of these data types. The feature can be useful for the following situations: - know the difference between one period of time and another - calculate the total time of some action That feature can also be used by `arrow-datafusion` for interval arithmetics. **Describe the solution you'd like** New functions for `IntervalYearMonthType`, `IntervalDayTimeType` and `IntervalMonthDayNanoType`: - add_day_time - add_year_months - add_month_day_nano - subtract_day_time - subtract_year_months - subtract_month_day_nano The functions `add_dyn` and `substract_dyn` start to support arithmetic between `Intervals`. **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
