Cut release to include `request` in exempt_when?

[sneakers-the-rat]

It looks like there was some work done a few years ago to pass request to a is_exempt handler here:

slowapi/slowapi/wrappers.py

Lines 48 to 52 in a72bcc6

	if self.exempt_when is None:
	return False
	if self._exempt_when_takes_request and request:
	return self.exempt_when(request)
	return self.exempt_when()

but the latest release is 0.1.9 which doesn't have it:

slowapi/slowapi/wrappers.py

Line 40 in 6547679

return self.exempt_when() if self.exempt_when is not None else False

any chance we can get an updated release that has that?
