kasplex addData添加json字符串

addData当前添加签名信息。如何添加json字符串？你能提供一个示例代码吗？

go语言示例：

builder := txscript.NewScriptBuilder()

builder.AddData(pubkh)

builder.AddOp(txscript.OpCheckSig)

builder.AddOp(txscript.OpFalse)

builder.AddOp(txscript.OpIf)

builder.AddData([]byte("kasplex"))

builder.AddData([]byte{0x01})

builder.AddData([]byte{0x00})

builder.AddData([]byte{0x00})

builder.AddData(jsonData)

builder.AddOp(txscript.OpEndIf)
