This project should use Unity project construction and use "Assets/Plugins/UniDi" folder for UniDi package

[tsgcpp]

Introduction

This is a proposal.
I think this project should use Unity project construction for some reasons.

• To make it easy to develop UniDi
  • Just open this project by Unity editor
• To separate distributed assets and unused files for Unity.
  • Distributed assets shoud be in Assets/Plugins/UniDi
  • Unused files should be outside Assets/Plugins/UniDi (ex: test scenes for SceneTestFixture, .github and CI yaml files, etc...)
• To make it available to add scenes to the build settings for SceneTestFixture tests
  • Tests like TestSceneContextEvents require scenes which are added to the build settings
  • If using Unity project construction, scenes can be added to the build settings without the distribution of the scenes
