compare.date

[yishairasowsky]

Thank you @perryvais @imad3v @tknuth @mayerantoine for your excellent work!
I see an example using two methods "string" and "exact".
But here I see that there is another method called "date". When I try to use "date" like this

compare_cl.date('dob', 'dob', label='dob')
compare_cl.exact('exclusion_date', 'exclusion_date', label='exclusion_date')

throws an error as follows:

ValueError: Left column is not of type datetime64[ns]
