AVIF & WEBP Converter
A package for automatically converting images to WebP and AVIF to improve performance and optimize website loading on MODX.

Based on github.com/commeta/modxWebpConverter, but completely redesigned and significantly expanded.

The github.com/rosell-dk/webp-convert library has been updated from 1.1.0 to 1.6.0
Support has been added for github.com/kornelski/cavif-rs

Device support check:
If the user supports WebP or AVIF, the following classes are automatically added to the html tag:

awc_support_webp or awc_support_avif

This allows you to use CSS selectors:

html.awc_support_avif :has(img) { ... }
html:not(.awc_support_webp) img { ... }

Also, if the format is not supported by the device, no substitution will occur.

Compatibility
Added substitution of new data-* attributes for compatibility with popular lazy-load and slider libraries.

Format Selection
Ability to switch between WebP and AVIF in the settings.

Settings
Turn the plugin on/off (off by default)
Disable image substitution for authorized users

Select conversion quality from 1 to 100 for webp/avif
Debug mode
