    Subclasses may implement this to add post processing of the decoded events.
    This will run after the normal decoding step and will only process decoded history events.
    This function should return a dict where values are tuples where the first element is the
    priority of a function and the second element is the function to run. The higher the
    priority number the later the function will be run.
    The keys of the dictionary are counterparties.
