* wip client core * hashing shared key in persisted details * native client using on-disk gateway details * ibid for socks5 * ibid for NR * nym sdk * non-wasm fixes * wasm * missed cargo fmt * fixed nym-connect build * changed serialization of the key hash to be more human readable * allowing some dead code * fixed gateway details deserializtion * removed needless borrow in wasm client * removed deadcode * exhaustive match on GatewaySetup after having loaded the keys
