Reject bool in datetime/date/duration integer fields

[Pitchfork-and-Torch]

Summary

bool is a subclass of int, so dt.replace(year=True) became year 1 and dt.add(days=True) added one day. Reject bool in add/set/replace and Duration construction. The tzinfo=True sentinel for keeping the current timezone is unchanged.

Bug

>>> import pendulum
>>> pendulum.datetime(2020, 5, 15).replace(year=True)
DateTime(1, 5, 15, ...)  # unexpected
>>> pendulum.datetime(2020, 5, 15).add(days=True)
DateTime(2020, 5, 16, ...)  # unexpected +1 day
>>> pendulum.duration(years=True)
Duration(days=365)  # unexpected

Test plan

• test_add_rejects_bool / test_replace_rejects_bool / test_set_rejects_bool
• test_duration_rejects_bool
• test_replace_tzinfo_true_still_allowed
• Date add/replace bool rejects
