Bug Description

After #152 "Full"" sized images inserted by users will still use the original jpeg image or (-scaled version for larger images) because the WebP version is not being generated. See #152 (comment).

Proposal to fix:

• Always generate a full sized WebP version when WebP output is active
• For larger images (over big_image_size_threshold), generate a -scaled.webp file

Steps to reproduce

1. Enable webp-uploads
2. Upload and insert an image, select full size in the image properties sidebar
3. view the post and check the image source

Expected:

• All image references are to .webp files

Actual

• some references are to a .jpg file.
