feat: add lens distortion

[damienmontastier]

This component introduces the LensDistortionEffect, which provides an abstraction for applying lens distortion with chromatic aberration blur. The <LensDistortionEffect> is specifically designed to add dynamic and immersive visual effects by distorting the scene with a customizable blur, enhancing artistic quality and realism.

• Easy to set up — simply include it in your <EffectComposerPmndrs> pipeline.
• Multiple options for controlling distortion intensity, principal point, focal length, and skew are available.
• Fully supports different blend functions for enhanced customization.

For more details, see Lens Distortion Effect on pmndrs.
