用法：

创建空交易单 CreateEmptyRawTransaction
        前置条件:
                获取需要发送的utxo
                获取接收地址和找零地址
                确定手续费以及找零数额
        步骤:
                使用utxo的交易哈希(txid)和输出索引(vout)填充TxIn结构体的Prevout字段
                使用接收地址和找零地址以及对应数额填充TxOut结构体的Address字段和Amount字段
                确认交易单版本号
                确认交易单锁定时间
                确认交易是否可以追加手续费(replaceable)
                获取空交易单
        调用方式:
                CreateRawTransaction([]TxIn, []TxOut, transactionVersion, lockTime, replaceable)
        Tips:
                txid使用的是小端模式，即查询交易时的端序
                交易单版本号为目前的默认版本号02
创建用于签名的交易单哈希 CreateRawTransactionHashForSign
        前置条件:
                获取需要发送的utxo
                获取接收地址和找零地址
                确定手续费以及找零数额
        步骤:
                使用utxo的交易哈希(txid)和输出索引(vout)填充TxIn结构体的Prevout字段
                使用接收地址和找零地址以及对应数额填充TxOut结构体的Address字段和Amount字段
                确认交易单版本号
                确认交易单锁定时间
                确认交易是否可以追加手续费(replaceable)
                获取前置交易的锁定脚本
                确认签名类型
                获取交易单
        调用方式:
                CreateRawTransactionHashForSign([]TxIn []TxOut, transactionVersion, lockTime, replaceable, signType)
        Tips:
                txid使用的是小端模式，即查询交易时的端序
                交易单版本号为目前的默认版本号02
                签名类型一般为signAll
本地交易单签名 SignEmptyRawTransaction
        前置条件:
                获取空交易单emptyTrans
                获取utxo的锁定脚本以及脚本对应的私钥
        步骤:
                使用锁定脚本与私钥填充TxUnlock结构体
                确定签名类型
        调用方式:
                SignRawTransaction(emptyTrans, []TxUnlock, sigType)
        Tips:
                TxUnlock结构体数组的顺序应该与空交易单的utxo的txid顺序保持一致
                签名类型一般为signAll
客户端交易单哈希签名 SignRawTransactionHash
        前置条件:
                获得用于签名的交易单哈希

                获取签名
        调用方式:
                SignRawTransactionHash(transForSig, []TxUnlock)
        Tips:
                TxUnlock结构体数组的顺序应该与空交易单的utxo的txid顺序保持一致
合并交易单 InsertSignaturesToEmptyRawTransaction
        前置条件:
                获得空交易单
                获得签名

        调用方式:
                InsertSignaturesToEmptyRawTransaction(emptyTrans, []SignaturePubkkey)
        Tips:
                签名数据结构体数组的顺序应该与utxo的txid顺序保持一致
交易单验签 VerifyRawTransaction
        前置条件:    
                获取签名后的交易单signedTrans
                获取utxo的锁定脚本
        步骤:
                使用锁定脚本填充TxUnlock结构体
        调用方式:
                VerifyRawTransaction(signedTrans, []TxUnlock)
        Tips:
                TxUnlock结构体数组的顺序应该与交易单的utxo的txid顺序保持一致
