feat: add timezone handling for datetime in pydantic (#578)

Browse Source 
If you add timezone information in the Field annotation for a datetime
then that will now be passed to the pyarrow data type.

I'm not sure how pyarrow enforces timezones, right now, it silently
coerces to the timezone given in the column regardless of whether the
input had the matching timezone or not. This is probably not the right
behavior. Though we could just make it so the user has to make the
pydantic model do the validation instead of doing that at the pyarrow
conversion layer.
