hypothesis.extra.pandas: generate timezone-aware datetime columns

[keewis]

In pydata/xarray#9174, I've been trying to find a way to generate timezone-aware datetime columns using pdst.column, where the entire column would have the same timezone: I believe pandas doesn't support varying timezones outside of the object dtype.

However, it doesn't seem like hypothesis.extra.pandas currently supports this using pdst.column (I didn't check whether the creation of timezone-aware datetime indexes would work, though).

Would it be possible to add something to that end?

Not sure how that would look API-wise, but in addition to a timezone strategy, I'd also like to be able to specify the datetime unit (since xarray is currently restricted to just nanosecond resolution).
