[feature request] Add GameObject.GetTags() extension

[lemoissonneur]

Hello !
Thank you for this package.
I think it would be a good addition to be able to get a list of Tags from a GameObject based on a TagContainer.

public static class TagExtensions
{
        ...
        public static Tag[] GetTags(this GameObject entity, TagsContainer tags)
        {
            Tag[] tagTable = new Tag[tags._tags.Length];
            int index = 0;

            for (int i = 0; i < tags._tags.Length; ++i)
            {
                if (entity.HasTag(tags._tags[i]))
                {
                    tagTable[index] = tags._tags[i];
                    index++;
                }
            }

            System.Array.Resize(ref tagTable, index);

            return tagTable;
        }
        ...
}

but it require the TagContainer tag array to be public.

public sealed class TagsContainer : ScriptableObject
{
	[SerializeField] public Tag[] _tags = null;
	...
}

use example :

using System.Collections.Generic;
using UnityEngine;
using ToolBox.Tags;

public class Example : MonoBehaviour
{
    public List<GameObject> myGameObjects = new List<GameObject>();
    public TagsContainer relevantTags;

    public List<GameObject> GetMatchingGameObjects(GameObject reference)
    {
        List<GameObject> matchingGameObjects = new List<GameObject>();

        Tag[] referenceTags = reference.GetTags(relevantTags);

        foreach(GameObject g in myGameObjects)
        {
            if (g.HasTags(referenceTags, true))
                matchingGameObjects.Add(g);
        }

        return matchingGameObjects;
    }
}

Hello again! :)

You can make fork and then make this changes. Sorry, but i don't found this feature useful to put it in master branch.
