Added inputs, outputs and feeAmount to /crosschain//walletbalance endpoints

The inputs and outputs contain a simpler version than the ones in the raw transaction, consisting of `address`, `amount`, and `addressInWallet`. The latter of the three is to know whether the address is one that is derived from the supplied xpub master public key.
