FutureWarning raised by lf_helpers

[aliakatas]

Reading some LF1 files raises the following warning:

lf_helpers.py:75: FutureWarning: DataFrame.set_axis 'inplace' keyword is deprecated and will be removed in a future version. Use `obj = obj.set_axis(..., copy=False)` instead df.set_axis(self._subheaders, axis=1, inplace=True)

Obviously not critical, just to make you aware in case you want to address it.

Environment:

• Python 3.9.1
• pandas=1.4.3
• floodmodeller-api=0.4.0
