FinRL/finrl/meta/preprocessor/preprocessors.py does not deal with minute data ?

[aymeric75]

Hi,

If I pass a dataframe with a column "datetime" to the FeatureEngineer class I get a AttributeError: 'DataFrame' object has no attribute 'date' error

And actually after having inspected the code I realized that it does not take into account scenario where a column with minutes (like datetime) is present.

Thanks
