 *
 A transaction body to vote on the validity of Threshold Signature Scheme
 (TSS) Messages for a candidate roster.

 - A `TssVoteTransactionBody` MUST identify the hash of the roster containing
 the node generating this TssVote
 - A `TssVoteTransactionBody` MUST identify the hash of the roster that the
 TSS messages is for
 - If the candidate roster has received enough yes votes, the candidate
 roster SHALL be adopted.
 - Switching to the candidate roster MUST not happen until enough nodes have
 voted that they have verified a threshold number of TSS messages from the
 active roster.
 - A vote consists of a bit vector of message statuses where each bit
 corresponds to the order of TssMessages as they have come through
 consensus.
 - The threshold for votes to adopt a candidate roster SHALL be at least 1/3
 of the consensus weight of the active roster to ensure that at least 1
 honest node has validated the TSS key material.
