Add support for auto-compound in kaspawallet send (#1951)
* Add GetUTXOsByBalances command to rpc

* Fix wrong commands in GetBalanceByAddress

* Moved calculation of TransactionMass out of TransactionValidator, so t that it can be used in kaspawallet

* Allow CreateUnsignedTransaction to return multiple transactions

* Start working on split

* Implement maybeSplitTransactionInner

* estimateMassIncreaseForSignatures should multiply by the number of inputs

* Implement createSplitTransaction

* Implement mergeTransactions

* Broadcast all transaction, not only 1

* workaround missing UTXOEntry in partially signed transaction

* Bugfix in broadcast loop

* Add underscores in some constants

* Make all nets RelayNonStdTxs: false

* Change estimateMassIncreaseForSignatures to estimateMassAfterSignatures

* Allow situations where merge transaction doesn't have enough funds to pay fees

* Add comments

* A few of renames

* Handle missed errors

* Fix clone of PubKeySignaturePair  to properly clone nil signatures

* Add sanity check to make sure originalTransaction has exactly two outputs

* Re-use change address for splitAddress

* Add one more utxo if the total amount is smaller then what we need to send due to fees

* Fix off-by-1 error in splitTrasnaction

* Add a comment to maybeAutoCompoundTransaction

* Add comment on why we are increasing inputCountPerSplit

* Add comment explaining while originalTransaction has 1 or 2 outputs

* Move oneMoreUTXOForMergeTransaction to split_transaction.go

* Allow to add multiple utxos to pay fee for mergeTransactions, if needed

* calculate split input counts and sizes properly

* Allow multiple transactions inside the create-unsigned-transaction -> sign -> broadcast workflow

* Print the number of transaction which was sent, in case there were multiple

* Rename broadcastConfig.Transaction(File) to Transactions(File)

* Convert alreadySelectedUTXOs to a map

* Fix a typo

* Add comment explaining that we assume all inputs are the same

* Revert over-refactor of rename of config.Transaction -> config.Transactions

* Rename: inputPerSplitCount -> inputsPerSplitCount

* Add comment for splitAndInputPerSplitCounts

* Use createSplitTransaction to calculate the upper bound of mass for split transactions
