Pull #271

github

Support batching any adapter RPC method, including eth_createAccessList

The adapter delegated batch_request to Ethereumex.HttpClient.batch_request/2,
which dispatches batch entries to named functions on Ethereumex.HttpClient -
so methods Ethereumex does not implement (like eth_createAccessList) crashed
with UndefinedFunctionError when batched.

Build the batch payload in the adapter itself through Ethereumex's generic
request/3 (deriving the JSON-RPC method name from the callback atom) and post
it directly, making every method the adapter supports batchable without
depending on Ethereumex's named function coverage. Map :create_access_list to
eth_createAccessList in Ethers.batch/2 and document it as batchable.
