avif encoding support is not perfect

[sommio]

aom can't encode jpeg (yuvj420p) and --pix-format doesn't work,
although it can be replaced with -sc-pix-format for now,
but av1an gives a new error when encoding webp and png.

Information

• ffmpeg 2:6.0-11.1
• av1an 0.4.1-1.2
• via ALHP

Reproduction

av1an -i test.jpg --pix-format yuv444p10le -o test.jpg.avif

av1an -i test.jpg --sc-pix-format yuv444p10le -o test.jpg.avif

av1an -i test.webp --sc-pix-format yuv444p10le -o test.webp.avif

av1an -i test.png --sc-pix-format yuv444p10le -o test.png.avif

Expected

• Ability to encode png and webp
• --pix-format works fine like ffmpeg's -pix_fmt

Actual

Why not encode using avifenc?
