[FEATURE] VFX PropertyBinder

[lgarczyn]

Is your feature request related to a problem? Please describe.

Right now, there are no easy interactions possible between VFX components and unity atoms.

Describe the solution you'd like

The VFX packages provides a very handy and powerful PropertyBinder system that makes linking VFX properties to things like transforms or colliders extremely easy.

It would be dead simple to add a package to atoms to implement binders for most atom types:

using UnityAtoms.BaseAtoms;
using UnityEngine;
using UnityEngine.VFX;
using UnityEngine.VFX.Utility;

namespace Atoms.VFXBinders
{
  [VFXBinder("Atoms/Float")]
  public class VFXFloatReferenceBinder : VFXBinderBase
  {
    [VFXPropertyBinding("System.Single")]
    [SerializeField] ExposedProperty property;
    [SerializeField] FloatReference value;

    public override bool IsValid(VisualEffect    component)
    {
      return !value.IsUnassigned && component.HasFloat(property);
    }

    public override void UpdateBinding(VisualEffect component)
    {
      component.SetFloat(property, value);
    }
  }
}

Also, currently there is no way to get a pretty name for a reference, so I'm stuck with this

    public override string ToString()
    {
      string valueName = value.IsUnassigned ? "null" : $"{AtomReferenceUsage.DisplayName(value.Usage)} {value.Value}";
      return $"Float : '{property}' -> {valueName}";
    }
