[Feature] Parse arbitrary transaction types (the Arbitrum issue)

### Component

rpc

### Describe the feature you would like

Currently get_block_by_hash() does parse a block, contaning a transaction type other than TxType. This does not allow to use get_block_by_hash() with Arbitrum, which uses private TX types.
Parsing arbitrary type was possible on ethers.rs.

Is there any workaround for the very issue?
If not, do you mean to add this functionality as, say, optional parameter?
