FutureWarning: The behavior of series[i:j] with an integer-dtype index is deprecated.

Hi,
Just tried the package and I get this warning.

/usr/local/lib/python3.9/dist-packages/valinvest/fundamentals.py:469: FutureWarning: The behavior of series[i:j] with an integer-dtype index is deprecated. In a future version, this will be treated as label-based indexing, consistent with e.g. series[i] lookups. To retain the old behavior, use series.iloc[i:j]. To get the future behavior, use series.loc[i:j].
return property[-years:].sum() / years
