What happened?

When running intraday strategies (e.g., intraday_strategy.py), multiple FutureWarnings are displayed:

qf-lib\qf_lib\data_providers\abstract_price_data_provider.py:280: FutureWarning: Minute.delta is deprecated and will be removed in a future version. Use pd.Timedelta(obj) instead                                                 
  frequency_delta = to_offset(frequency.to_pandas_freq()).delta.value

The warning appears many times (once for each data request) when accessing the .delta attribute of a Minute offset object.
