maxSigners: the number of participants that are refreshing their
shares. It can be smaller than the original value, but still equal to or
greater than minSigners.

original value for the group (i.e. the refresh process can't reduce
the threshold).
It returns the SecretPackage that must be kept in memory by the participant
for the other steps, and the Package that must be sent to each other
