Update hypotheses and common_hypothesis by pre_process_poi

[dachengx]

Previously only the generate_values are updated by update_poi:

alea/alea/runner.py

Lines 172 to 181 in cee1e71

	def generate_values(self, value: Dict[str, float]) -> None:
	if not all([isinstance(v, (float, int)) for v in value.values()]):
	raise ValueError(f"generate_values should be a dict of float! But {value} is provided.")
	# update poi according to poi_expectation
	if "poi_expectation" in value:
	self.input_poi_expectation = True
	value = self.update_poi(self.model, self.poi, value, self.nominal_values)
	else:
	self.input_poi_expectation = False
	self._generate_values = value

This PR also updates "poi_expectation" in hypotheses and common_hypothesis.

Thanks a lot @dachengx for this quick implementation! I tried it with a few toys and it works flawlessly. I left two minor comments that you can implement if you find them useful, otherwise just go ahead and merge 😊

name is a bit generic. Maybe something like called_by_name instead to make it a bit clearer? But I can also live with name :D

[dachengx]

I updated it to attribute_name.
