Add support for psetv2 (#189)

* added factory method FromPublicKeys for creating multiscript payment * define psetv2 format * pset desr - untested version * fixes added - not verified * validation * first version passing test case * psetv2 serialization * refactor * creator and constructor role * blinder role * updater role * signer * fix * add nigiri gh action * separate signer role from updater * finalizer role added * extractor role added * fix timelock validation * signer validation added * CreateAssetBlindProof * decouple psetv2 from confidential * decouple blindProofsValid from confidential pkg * verify blinding, pset to unsigned tx, bugs * bug fixing * fix bugs * fix bug * fix ComputeAndAddToScalarOffset bug * Rename methods of elementsutils & bufferutil * Remove useless fils * Refactor psetv2 * Add checks && Polish errors * Drop travis * Split Blind into BlindLast|BlindNonLast * Fix serialization * Fixes after review * Fix method name * Fix global (de)serialization * Add tests for creator role * Fix swap test * Add NewBlinderHandlerFromOwnedInputs factory * Fix usage of ecdh nonce for last value rangeproof * Return unconf output if it's not confidential instead of nil * Remove too much strict validation check * Allow to add dummy outputs to partial tx * Fix blinding dummy outputs + dedicated test * Update CI badge in readme * Fix unsigned tx version * Fix issuance blindingi nonce deserialization * Fix signing psetv2 test txs * Fix signer * Split BlinderHandler into validator and generator & validate all blinding proofs * Fixes * Do not use bitset fields for now * Fixes * Revert sighash change * Fixes * Fixes * Set TxModifiable flag by creator * Add and make mandatory usage of updater.AddInUtxoRangeProof * Fix out.NeedsBlinding Co-authored-by: sekulicd <sekula87@gmail.com>
