Add ENV setting for AVIF speed parameter (#605)

* Add ENV setting for AVIF speed parameter

* Add AVIF to image format docs

* Only use Speed on supported VIPS version

* Probably need the method signature in go to have speed

 * `IMGPROXY_ENABLE_AVIF_DETECTION`: enables AVIF support detection. When the file extension is omitted in the imgproxy URL and browser supports AVIF, imgproxy will use it as the resulting format;

 **📝Note:** imgproxy prefers AVIF over WebP. This means that if both AVIF and WebP detection/enforcement are enabled and the browser supports both of them, AVIF will be used.
