Pandas SettingWithCopyWarning

[MauritsDescamps]

When I run get_trend_stats I get the following warning multiple times:

featexp/base.py:23: SettingWithCopyWarning
A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_indexer,col_indexer] = value instead

The origin of the problem is the fact that get_grouped_data changes its input dataframe. It might be better to copy the input data before doing anything with it.

Setup:

• Python 3.8.13
• featexp 0.0.7
• Pandas 1.4.3
