Add anvil `--dump-event`

[samlaf]

Component

Anvil

Describe the feature you would like

We setup an anvil localnode for integration tests, deploy contracts, register some txs, and then save this state. The problem is that the events have meaningful information that needs to be queried from offchain code. However, anvil only has a --dump-state feature, and when starting anvil with anvil --load-state saved_state.json, all receipts are lost, and the chain is restarted at block 0.

Would be useful to have a flag --dump-receipts that would also dump the receipts in a file, and could restart the chain with those events. Is that possible?
