cannot convert slice to array

[Villaquiranm]

Slice-to-Array Casting Limitation

Description

In golang you're able to do (https://go.dev/play/p/1gERcS_9z_l)

package main

import "fmt"

func main() {
	var byteArray []byte = []byte{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}
	arrayTwenty := [20]byte(byteArray)
	fmt.Println(arrayTwenty)
}

trying to do something equivalent on Gnolang,
you can go to gnovm/stdlibs/std/crypto.go and modify convertTo20Byte function as follows:

func convertTo20Byte(in []byte) [20]byte {
	return [20]byte(in)
}

running
gno test . on sdt package will result on

.: test pkg: panic: cannot convert []uint8 to ArrayKind

This is a recent feature in Go as well, so implementation of this feature is a non-priority but I think we can accept a PR.
