This commit uses the now created PSBTWalletMixin and additionally
creates a SNICKERWalletMixin, and adds a SNICKERReceiver object
to jmclient. A test of the end to end workflow of create and then
co-sign a SNICKER coinjoin as per the draft BIP is in test_snicker.
Additional changes:
updated python-bitcointx dependency to >=1.0.5
Minor refactoring of callbacks in tests and additional redeem
script checks to PSBTWalletMixin.sign_psbt.
Note that this work replaces #403 .
Subclassed btcointx.CKeyBase to create a privkey type
that uses our signing code.
These are then used to allow signing of inputs in
transactions owned by our wallet.
Created a PSBTWalletMixin to perform the above function,
and added it to our three wallet types.
Wrote a detailed creation, sign and broadcast test
for a psbt using utxos from within and outside the wallet.
Detailed tests across all 3 wallet types for psbt
Tests cover also mixed inputs of different
types and owned/unowned. Direct send now exported to be used
in tests rather than only script usage, also supports returning
a tx object rather than only a txid.
