Hare: oracle explicitly depends on hare round number

[jonZlotnik]

Description

The Oracle explicitly depends on "k". In the code, this is the total number of rounds since the pre-round. We should rename this parameter to be some other kind of identifier such that the oracle can be used to prove eligibility for things other than hare rounds. Termination certification, for example, requires oracle-chosen committee members.
