> Hi!
> When I create a pandas interval series and then convert it into a pyarrow array and then try to convert that pyarrow array back to pandas I'm getting an attribute error. The error says that Series object has no attribute `to_pandas`.
> I've added the code that produces the error below.
> {code:java}
> // code placeholder
> In [14]: x = pd.Series([pd.Interval(0, 1), pd.Interval(2, 3), pd.Interval(3, 4)])
> In [15]: y = pa.Array.from_pandas(x)
> In [16]: y.type
> Out[17]: ArrowIntervalType(extension<pandas.interval>)
> In [17]: y.to_pandas()
> ---------------------------------------------------------------------------
> AttributeError Traceback (most recent call last)
> <ipython-input-17-48c5b189df56> in <module>

> It would be great tp have a method to convert from a pyarrow interval array directly into a pandas series.
