The wallet is currently created without setting any lookahead value for the keychain. This implicitly makes it a lookahead of 0. As this is a high-level interface we should avoid footguns and aim for a reasonable default. Instead of simply patching it for wallet, we alter `KeychainTxOutIndex` to have a default lookahead value. Additionally, instead of a per-keychain lookahead, the constructor asks for a `lookahead` value. This avoids the footguns of having methods which allows the caller the decrease the `lookahead` (and therefore panicing). This also simplifies the API.
