Performs the third and final part of the refresh procedure for the
participant holding the given SecretPackage, given the received
round1::Packages and round2::Packages received from the other
participants.
round2Packages maps the identifier of each other participant to the
Package they sent to the current participant (the owner of
secretPackage). These identifiers must come from whatever mapping the
participant has between communication channels and participants, i.e. they
must have assurance that the Package came from the participant
with that identifier.
oldPubKeyPackage and oldKeyPackage are the old values from the
participant, which are being refreshed.
It returns the refreshed KeyPackage that has the long-lived key share
for the participant, and the refreshed PublicKeyPackage that has public
information about all participants; both of which are required to compute
FROST signatures. Note that while the verifying (group) key of the
PublicKeyPackage will stay the same, the verifying shares will change.
