Add finalize_psbtmethod to wallet

[rustaceanrob]

Description

Add the finalize_psbt method on the wallet. One of the methods in #596

Notes to the reviewers

We keep the SignOptions default here considering that's how it is used for sign. The only reason SignOptions is used is whether we assume the height in the PSBT or not.

ACK 9ea6013.

Awesome! I think that closes #469.

Ideally, @andreasgriffin can test if this resolves his issue, but I believe this should be sufficient

Unfortunately not.
My test code (with an unrelated wallet seed):

import bdkpython as bdk 
import datetime



network = bdk.bitcoin.Network.REGTEST
electrum = bdk.bdk.ElectrumClient("my-server:50001")

mnemonic = bdk.Mnemonic.from_string('bacon '*24)
print(mnemonic )


descriptor = bdk.Descriptor.new_bip84(
            secret_key=bdk.DescriptorSecretKey(network, mnemonic, ''),
             keychain=bdk.KeychainKind.EXTERNAL,
             network=network,
)


change_descriptor = bdk.Descriptor.new_bip84(
            secret_key=bdk.DescriptorSecretKey(network, mnemonic, ''),
             keychain=bdk.KeychainKind.INTERNAL,
             network=network,
)

 
print(f'xpub {descriptor }')



wallet = bdk.Wallet(
             descriptor=descriptor,
             change_descriptor=change_descriptor,
             network=network, 
             connection=bdk.Connection.new_in_memory()
         )

I get

The PSBT from #469 should not require the source wallet to be finalized.
