Filter out candidates whose hashes aren't allowed, and return a new
list of candidates.
If at least one candidate has an allowed hash, then all candidates with
either an allowed hash or no hash specified are returned. Otherwise,
the given candidates are returned.
Including the candidates with no hash specified when there is a match
allows a warning to be logged if there is a more preferred candidate
with no hash specified. Returning all candidates in the case of no
matches lets pip report the hash of the candidate that would otherwise
have been installed (e.g. permitting the user to more easily update
their requirements file with the desired hash).

Function to pass as the `key` argument to a call to sorted() to sort
InstallationCandidates by preference.
Returns a tuple such that tuples sorting as greater using Python's
default comparison operator are more preferred.
The preference is as follows:
First and foremost, candidates with allowed (matching) hashes are
always preferred over candidates without matching hashes. This is
because e.g. if the only candidate with an allowed hash is yanked,
we still want to use that candidate.
Second, excepting hash considerations, candidates that have been
yanked (in the sense of PEP 592) are always less preferred than
candidates that haven't been yanked. Then:
If not finding wheels, they are sorted by version only.
If finding wheels, then the sort order is by version, then:
1. existing installs
2. wheels ordered via Wheel.support_index_min(self._supported_tags)
3. source archives
If prefer_binary was set, then all wheels are sorted above sources.
Note: it was considered to embed this logic into the Link
comparison operators, but then different sdist links
with the same version, would have to be considered equal
