parse_date behavior change in version 0.7.2

[KaworuNagisa-fr]

Hello,

I noticed a change in the way parse_date works in the last release. Previously, using parse_date with a datetime string worked, returning only the date part :

>>> import isodate
>>> dt = '2024-10-11T13:00:00'
>>> isodate.parse_date(dt)
datetime.date(2024, 10, 11)

This was very useful when working with a module like FullCalendar which returns date strings OR datetime strings according to the view.

In the last version, this no longer works :

>>> import isodate
>>> dt = '2024-10-11T13:00:00'
>>> isodate.parse_date(dt)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Env\Pyramid_crit_py312\Lib\site-packages\isodate\isodates.py", line 194, in parse_date
    raise ISO8601Error("Unrecognised ISO 8601 date format: %r" % datestring)
isodate.isoerror.ISO8601Error: Unrecognised ISO 8601 date format: '2024-10-11T13:00:00'

The cause being the new "add_re" function which adds "\A" and "\Z" at the start and end of the regexes.

def add_re(regex_text):
    cache_entry.append(re.compile(r"\A" + regex_text + r"\Z"))

Removing the "\Z" fixes the issue.

Maybe this is intentional, though...

Thanks a lot
