fix(iota-types): use digest for ConsensusTransactionKey of MisbehaviorReport

[cyberphysic4l]

Description of change

The ConsensusTransactionKey for MisbehaviorReport uses authority name and the checkpoint sequence number, but this may cause ambiguity if an authority submits more than one report in one checkpoint. It is better to use the digest of the misbehavior report.

This PR adds a digest to the misbehavior reports and uses this for the consensus transactions key.
