Behavior for day checking is incorrect

[kenahoo]

The docs for crontab (https://man7.org/linux/man-pages/man5/crontab.5.html) say this:

Commands are executed by cron(8) when the 'minute', 'hour', and 'month of the year' fields match the current time, and at least one of the two 'day' fields ('day of month', or 'day of week') match the current time (see "Note" below).

and here's the Note:

Note: The day of a command's execution can be specified in the following two fields — 'day of month', and 'day of week'. If both fields are restricted (i.e., do not contain the "*" character), the command will be run when either field matches the current time. For example, "30 4 1,15 * 5" would cause a command to be run at 4:30 am on the 1st and 15th of each month, plus every Friday.

However, the pycron functionality is different - it requires that both the fields match:

>>> import pycron
>>> from datetime import datetime
>>> dt = datetime(2022, 6, 23)  # A Thursday
>>> pycron.is_now('* * 22 * thu', dt)
False
>>> pycron.is_now('* * 23 * thu', dt)
True
>>> pycron.is_now('* * 23 * fri', dt)
False
