network bytes is short on Route Monitoring parsing

[lfundaro-do]

Hi. I'm at v3.34.0 and trying to parse a BMP message but failing on parsing the NLRI IPv4AddressPrefix
here's a code snippet that reproduces the issue:

package main

import (
	"log"

	"github.com/osrg/gobgp/v3/pkg/packet/bmp"
)

func main() {
	b := []byte{0x3, 0x0, 0x0, 0x0, 0x5e, 0x0, 0x3, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0xff, 0xdd, 0x19, 0x41, 0xa, 0x28, 0x3, 0xc8, 0x67, 0xab, 0x36, 0x6a, 0x0, 0x7, 0x10, 0x98, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0x0, 0x2e, 0x2, 0x0, 0x0, 0x0, 0xe, 0x40, 0x1, 0x1, 0x0, 0x40, 0x2, 0x0, 0x40, 0x3, 0x4, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0xb, 0xf2, 0x1f, 0xa, 0x28, 0x3, 0xe8}
	_, err := bmp.ParseBMPMessage(b)
	if err != nil {
		log.Fatalf("Error parsing BMP message: %v", err)
	}
}

Is this a problem on the BMP message itself ? or rather a bug on the parsing of this message ? I would greatly appreciate your help.
