Function load_prefix_sets_with_provider 

pub fn load_prefix_sets_with_provider<Provider>(
    provider: &Provider,
    range: RangeInclusive<BlockNumber>,
) -> Result<TriePrefixSets, ProviderError>
where
    Provider: ChangeSetReader + StorageChangeSetReader + DBProvider,

Load prefix sets using a provider that implements [ChangeSetReader]. This function can read changesets from both static files and database.

Storage keys from changesets are tagged as Plain or Hashed by the reader, so callers need not pass a use_hashed_state flag. Addresses are always hashed.
