Use lossless encoding when supported

The batch workspace is ready. Image encoding becomes available after the verified browser engine is loaded.

JPEG XL input may contain lossless or lossy pixels, alpha, wide color, and high dynamic range data.

AVIF output favors small files and supports alpha and animation, but encoding can take longer.
