[Feature] Introduce alloy-compat

Describe the feature you would like

I've written alloy-compat, which allows convertions between alloy and ethereum_types types:

use alloy_compat::Compat as _;

// from alloy to ethereum_types
let address = alloy::address!("deadbeefdeadbeefdeadbeefdeadbeef00000000");
let _: eth::Address = address.compat();

// from ethereum_types to alloy
let hash = eth::H256::zero();
let _: alloy::B256 = hash.compat();

// integers are supported
let int = eth::U128::MAX;
assert_eq!(alloy::U128::MAX, int.compat());

Might be useful to fold it in here - this issue is for guaging your interest in that
