You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: hexdump.go
    path of file: ./repos/ipsw/internal/utils
    
    the code of the file until where you have to start completion: package utils

import (
	"encoding/hex"
	"errors"
	"io"
	"regexp"
	"strings"

	"gi
    
func HexDump(data []byte, vaddr uint64) string {
	if len(data) == 0 {
		return ""
	}

	var buf strings.Builder
	// Dumper will write 79 bytes per complete 16 byte chunk, and at least
	// 64 bytes for whatever remains. Round the allocation up, since only a
	// maximum of 15 bytes will be wasted.
	buf.Grow((1 + ((len(data) - 1) / 16)) * 79)

	dumper := Dumper(&buf, uint(vaddr))
	dumper.Write(data)
	dumper.Close()
	return colorZeros(buf.String())
}
