Describe the feature you would like

for historic blocks we currently need to acquire a write lock

in case we need to fetch the state from disk:

this is very inefficient because it bottlenecks concurrent requests < current.height.

this can be improved in various ways,

• easiest solution would be two step locking

1. write lock and ensure state is initialized if missing:

   foundry/crates/anvil/src/eth/backend/mem/storage.rs

   Lines 164 to 166 in 88c9b7f

   	if let Some(state) = self.on_disk_states.get_mut(hash) {
   	if let Some(cached) = self.disk_cache.read(*hash) {
   	state.init_from_snapshot(cached);

2. read lock to fetch it
