Problem Description
When using pandas pd.Timedelta function, if the unit keyword is mis-typed as units, then no error or warning is raised (I assume as it's passed down through **kwargs to datetime.timedelta).
So for example pd.Timedelta(1, unit='hours') returns Timedelta('0 days 01:00:00'). All good there. But if a user were to misremember the keyword and instead foolishly type in pd.Timedelta(1, units='hours') no warning will be raised, but default units of nano-seconds will be used and this will return: Timedelta('0 days 00:00:00.000000001').
This is clearly user-error (they could read the correct spelling of the keyword in the docs) - and is perhaps unreasonable feature to request, but can result in quite subtle bugs - as the type returned is correct, but of a very different size to that expected.
Feature Description
The list of available kwargs is quite short https://pandas.pydata.org/docs/reference/api/pandas.Timedelta.html - so could add a check that there aren't any others sneaking through, and raise a warning if so.
Alternative Solutions
Expect users not to mis-spell keywords :)
