* Fix eth/common & web3 related deprecation warnings for fluffy This commit uses the new types in the new eth/common/ structure to remove deprecation warnings. It is however more than just a mass replace as also all places where eth/common or eth/common/eth_types or eth/common/eth_types_rlp got imported have been revised and adjusted to a better per submodule based import. There are still a bunch of toMDigest deprecation warnings but that convertor is not needed for fluffy code anymore so in theory it should not be used (bug?). It seems to still get imported via export leaks ffrom imported nimbus code I think. * Address review comments * Remove two more unused eth/common imports
