Looks good to me!
Just in case, some simulation tests are broken, but probably it is ok for this PR, since I don't see the snapshots update included that is required for ChangeEpochV4 execution.

Just to double-check the condition, from the related message, it looks like we need to check that scorer_version is set when score_based_rewards is enabled.

You're right, thanks for catching that.

Description of change
Enables the creation of a new version of advance epoch transaction and new advance epoch function in iota-framework to modify rewards based on scores. The existing validator reporting system remains whereby rewards can be slashed entirely when a validator is reported. Now we additionally modulate the rewards with the score provided as an argument to the new version of the advance epoch function.
