Please version bump pandas in requirements file

[mttpgn]

Hello,

Your requirements.txt file allows any version of pandas above 0.24.0.

However, in your utils.py file, you twice invoke the pandas read_csv function with the on_bad_lines argument, an argument which was only introduced in pandas 1.3.0.

As a result, anyone running yfinance with a version of pandas greater than or equal to 0.24.0 but lower than 1.3.0 will experience a crash with the following error:

    df = _pd.read_csv(fp, index_col="Ticker", on_bad_lines="skip")
TypeError: parser_f() got an unexpected keyword argument 'on_bad_lines'

Please bump the version of pandas in your requirements.txt file to say
pandas>=1.3.0

It would be nice to update requirements to python 3.7+ too, since apparently pandas last version to support python 3.6 is v==1.3.0
