Function replay_corpus_to_showmap

    executor: &Executor<FEN>,

    fuzzed_function: Option<&Function>,

Replay every corpus entry under corpus_dir and emit showmap files.

fuzzed_function is set for stateless fuzz tests; fuzzed_contracts is set for invariant tests (txs are committed between calls in that case). dynamic lets invariant replay register contracts deployed mid-sequence so follow-up calls into them aren’t dropped.
