are we ok switching from SVG to webp (binary, non-scalable) format? What is the size reduction?

These images were originally hardware drawings generated using AutoCAD and they failed CI (whenever edits are made to the RSTs containing the images) because of image size > 250kb. Although @mirjaku tried reducing their sizes, it could not be made below 250 kb. Now with this webp format (as per your suggestion in the JIRA NCSDK-22370), these images can be made lesser in size (<250 kb) with the same quality.
