请问在这段示例代码中，0xF23F9FD2 代表什么，如何设置输出的 gas

[E0001]

// psbt
var inputs []*bitcoin.TxInput
inputs = append(inputs, &bitcoin.TxInput{
	TxId:              "46e3ce050474e6da80760a2a0b062836ff13e2a42962dc1c9b17b8f962444206",
	VOut:              uint32(0),
	Sequence:          1,
	Amount:            int64(546),
	Address:           "2NF33rckfiQTiE5Guk5ufUdwms8PgmtnEdc",
	PrivateKey:        "cPnvkvUYyHcSSS26iD1dkrJdV7k1RoUqJLhn3CYxpo398PdLVE22",
	MasterFingerprint: 0xF23F9FD2,
	DerivationPath:    "m/44'/0'/0'/0/0",
	PublicKey:         "0357bbb2d4a9cb8a2357633f201b9c518c2795ded682b7913c6beef3fe23bd6d2f",
})

var outputs []*bitcoin.TxOutput
outputs = append(outputs, &bitcoin.TxOutput{
	Address: "2NF33rckfiQTiE5Guk5ufUdwms8PgmtnEdc",
	Amount:  int64(100000),
})
psbtHex, err := bitcoin.GenerateUnsignedPSBTHex(inputs, outputs, network)
if err != nil {
	// todo
	fmt.Println(err)
}
fmt.Println(psbtHex)

This one doesn't support gas Settings, so you need to calculate inputs and outputs in advance.

[yanminmin]

MasterFingerprint is only supported by keystone.You can ignore this attribute

[E0001]

MasterFingerprint 仅受 keystone 支持。您可以忽略此属性

Okay, thank you, big shot
