ENH: add webp support to IPython.display.Image and complete identification of JPEG,PNG,GIF,WEBP image types by initial bytes (#14526)...

ENH: add webp support to IPython.display.Image and complete identification of JPEG,PNG,GIF,WEBP image types by initial bytes (#14526) - So that `Image('./example.webp')` does not raise a `"Cannot embed the 'webp' image format"` error. - So that matplotlib animations saved as .webp images work (e.g. when ffmpeg+h264 isn't working).
