Substring can't handle utf8 characters

[trim21]

package main

import (
	"fmt"

	"github.com/samber/lo"
)

func main() {
	result1 := lo.Substring("你好，世界", 0, 2)

	fmt.Printf("%s\n", result1)
}

when processing string, it's expected to do something like this: string(lo.Subset([]rune(s), start, end))

Cutting on codepoint boundaries could be counted as wrong as well if combining codepoints are not handled as well.

@samber new release please?

Sorry, saw the new tag.

The v1.38.0 release failed. I just made a new version: v1.38.1.
