Enable AVIF for GD on PHP 8.1 (#375)

README.md

@@ -301,6 +301,7 @@ Here's the list of all the supported environment variables:
 | | `IPE_KEEP_SYSPKG_CACHE=1` | By default the script will clear the apt/apk/pear cache in order to save disk space. You can disable it by setting this environment variable |
 | lzf | `IPE_LZF_BETTERCOMPRESSION=1` | By default `install-php-extensions` compiles the `lzf` extension to prefer speed over size; you can use this environment variable to compile it preferring size over speed  |
 | event | `IPE_EVENT_NAMESPACE=`... | By default the `event` classes are defined in the root namespace. You can use this environment variable to specify a custom namespace |
+| gd | IPE_GD_WITHOUTAVIF=1 | Since PHP 8.1, gd supports the AVIF format. Enabling it requires compiling libaom/libdav1d/libyuv/libavif, which is time-consuming. You can disable AVIF support by setting this environment variable |
