Add support for Arrow Timestamp and Date32 in DataFrame

[vthemelis]

Fixes: #7260
Fixes: #7261

Timestamp contains UTC information so it makes sense to capture it in DateTimeOffset rather than DateTime.

Also, capture Date32 as a DateOnly if we're in .NET 6 (DateOnly is missing from .NET standard at this point).

I think I'm happy with the coverage report. The lines that matter are covered.

[michaelgsharp]

Just some minor changes but otherwise looks good to me.

Hi @michaelgsharp, would you mind having another look at this?

[vthemelis]

Hi @michaelgsharp , would you be able to have a look at this?

@michaelgsharp could you have another look? I addressed all of your comments so should be straightforward to review.
