pandas TimeDelta formatting changed

Version checks

• I have checked that this issue has not already been reported.
• I have checked that this bug exists on the latest version.

Reproducible Example

See also: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.Timedelta.html

Deprecated since version 2.2.0: Values H, T, S, L, U, and N are deprecated in favour of the values h, min, s, ms, us, and ns.

Current behaviour

The code uses _TIMESTR = {"D": "days", "H": "hours", "T": "minutes", "S": "seconds"}

Desired behaviour

Update _TIMESTR, maybe with additional check to support older pandas versions?
