squidge_image helper function. This dynamically checks if an .avif or .webp file is available on the file system
and returns the output.
Function
/**

* (such as a JPG), the .avif file, the .webp file (if to exist on the file system).

* Appropriate elements for image sizes with max widths.
* Finally, the main be outputted with alt and title text.
*
