Extract minimal Rialto-Sub and Millau-Sub clients (#365)
* extracting sub clients * fmt + lost docs * revert enum BridgeInstance * apply suggestions from review * explicite debug impl * remove unused imports from Millau * fix typo * fix instance + API name * Update relays/ethereum/src/ethereum_sync_loop.rs Co-authored-by: Hernando Castano <HCastano@users.noreply.github.com> * separate crates for millau and rialto client * cargo fmt * fix * fmt * remove no_std support * fix compilation again * Update relays/substrate-client/Cargo.toml * Update relay clients to Substrate 2.0 Co-authored-by: Hernando Castano <HCastano@users.noreply.github.com> Co-authored-by: Hernando Castano <castano.ha@gmail.com>
