v2.0.0-preview8 Fix libwebp vulnerability and update all dependencies

Please update immediately if you process untrusted images with Imageflow. See GHSA-7vpr-3ppw-qrpj for more information.

Changes

• This release requires libc 2.31 or higher (such as Ubuntu 20+) on linux and macOS 11 or higher. These restrictions are due to the oldest supported versions of those platforms (which is reflected on Github Actions).
• All dependencies have been updated to their latest stable versions
• imageflow_tool requires valid UTF-8 paths passed to --in and --out, rather than silently dropping invalid characters.

v2.0.0-preview5 - Add &srset syntax; make webp read &quality, update dependencies

NOTE: linux nuget packages are now built on Ubuntu 20.04, since Ubuntu 18.04 is no longer available on GitHub. This may break older platforms.

• Add &srcset syntax
• Make webp read &quality if &webp.quality is missing
• Update dependencies
