UPM package for the immediate mode GUI library, Dear ImGui (https://github.com/ocornut/imgui).

• Add package from git URL: https://github.com/viliwonka/dear-imgui-unity.git .
• Add a DearImGui component to one of the objects in the scene.
• When using the Universal Render Pipeline, add a Render Im Gui Feature render feature to the renderer asset. Assign it to the render feature field of the DearImGui component.
• Subscribe to the ImGuiUn.Layout event and use ImGui functions.
• Example script:

  using UnityEngine;
  using ImGuiNET;
  
  public class DearImGuiDemo : MonoBehaviour
  {
      void OnEnable()
      {
          ImGuiUn.Layout += OnLayout;
      }
  
      void OnDisable()
      {
          ImGuiUn.Layout -= OnLayout;
      }
  
      void OnLayout()
      {
          ImGui.ShowDemoWindow();
      }
  }

This package uses Dear ImGui C bindings by cimgui and the C# wrapper by ImGui.NET.
