Support for temporal methods for Column

[amrit110]

Hi! Could there be support to perform temporal computations like (https://pola-rs.github.io/polars/py-polars/html/reference/series/temporal.html) on a column if its a datetime type?

So the use case would be something like this:

def compute_years(df, col_name, new_col_name):
    df_std = df.__dataframe_consortium_standard__()
    dt_col = df_std.get_column_by_name(col_name)
    years_col = dt_col.dt.year() # not sure if this is the API we want, but something like that
    df_std = df_std.insert_column(years_col.rename(new_col_name))

    return df_std.dataframe

Yeah your description there seems to cover it! Yeah please do add me to the call. Would love to listen in, we are adopting the array and dataframe API standards in our project which has some processing functions for clinical ML pipelines as well as evaluation functions (https://github.com/VectorInstitute/cyclops).
