• Shaders: fix differences between SRP and Built-in shaders.

Added

• Core: display more explicit warnings (console and editor), mainly when there are too much NeuroTags in the scene.
• Core: new ContactGradeEvent and methods GetContactGrade() and GetNormalizedContactGrade().
• Editor: new Welcome panel displayed on SDK importation, asking the user if Unity should add the example scenes to build settings.
• Shaders: add Metallic and Glossiness properties to SRP Lit shaders.
• Calibration: CalibrationGrade enumeration has a new UNDEFINED value.

• Calibration scene : remove unused SelectedDeviceStep.
• Core: [BREAKING] remove OTAEvent class.
