Changes look good, just needs a rebase. Quite a few conflicts. |

Description
This Pr adds in the ability to send and claim HTLC transactions.
This is added to the console wallet UI and GRPC commands.
UI:
tari_console_wallet --command "init-sha-atomic-swap <Amount> <Bob pubkey> <Message>"This is used to initialize an atomic swap for the XTR side
tari_console_wallet --command "finalise-sha-atomic-swap <Output hash> <pre_image hex>"This is used to finalize and claim an HTLC transaction for the XTR side.
GRPC:
rpc SendShaAtomicSwapTransaction(SendShaAtomicSwapRequest) returns (SendShaAtomicSwapResponse);This is used to initialize an atomic swap for the XTR side
rpc ClaimShaAtomicSwapTransaction(ClaimShaAtomicSwapRequest) returns (ClaimShaAtomicSwapResponse);This is used to finalize and claim an HTLC transaction for the XTR side.
Motivation and Context
This is the first step in allowing Atomic swaps for Tari and coins that have SHA256 as a pre_image.
Currently, the available commands in this PR and tools available we can do the happy path of an atomic swap for:
Bitcoin
Bitcoin Cash (Bitcoin ABC, Bitcoin Unlimited, Bitcoin XT)
Decred
Litecoin
Monacoin
Particl
Qtum
Vertcoin
Viacoin
Zcoin
How Has This Been Tested?
Added unit and cucumber tests for the Tari side.
Did a manual XTR BTC atomic swap
XTR UTXO hash:
