Repeated fields not packed by default

[aleksej825]

protobuf.js version - 7.5.0;
nodejs - 20.15.0.

The library encodes repeated fields as expanded by default. The issue is similar to this.

Code example:

import proto from 'protobufjs';

// Proto file
const proto_file = `syntax = "proto3";

message TestMessage{
    uint32 num = 1;
    repeated uint32 array = 2;
}`;

const array = new Array(3);

array.push(1);
array.push(2);
array.push(3);

const data = {
  num: 1,
  array
};

let obj;

const root = proto.parse(proto_file, { keepCase: true }).root; // or use Root#load

obj = root.lookupType('TestMessage');

const converted = obj.fromObject(data);
const result = obj.encode(converted).finish();
const temp = new Uint8Array(result);

console.log(temp.toString());

Actual result:
8,1,16,0,16,0,16,0,16,1,16,2,16,3

Expected result:
8,1,18,3,1,2,3
