Introduce a new crate evm_rpc_types that will contain all Candid types necessary to interact with the EVM RPC canister. As a first step for #243 :

Introduce Nat256 as a wrapper around a Nat that is guaranteed to have the same encoding/decoding as a Nat, while ensuring that it fits in a U256 bits.
As an example, refactor eth_fee_history so that the public API only uses types from the new evm_rpc_types crate .
