    datetime.(from_excel, to_excel): drop excel bug workaround · b8e92927806e

    The specification is clear on how to (de)serialize dates in the 1900
    date system. Instead of attempting to follow what Excel does (which we
    can't do fully anyway), let's follow the specification. This increases
    interoperability and allows correct timedelta calculations for time
    differences above 60 days.
