Performs the third and final part of the distributed key generation protocol
for the participant holding the given SecretPackage, given the
received round1::Packages and round2::Packages received from the
other participants.
round1Packages must be the same used in part2().
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.
It returns the KeyPackage that has the long-lived key share for the
participant, and the PublicKeyPackage that has public information about
all participants; both of which are required to compute FROST signatures.
