Add human readable representations of txs and PSBTs

Human readable representation for CTransaction
objects in jmbitcoin.secp256k1_transaction.py and for
PartiallySignedTransaction objects in jmclient.wallet.
PSBTWalletMixin, use of these in maker, taker, direct
send and in tests. Users should note that PSBT human
readable representations can in some cases be really
huge.
