In the JPEG decoder, use `bytes_per_line` instead of `width` for address calculations, to allow for bigger framebuffers. When calling jpeg_decode(), add an offset to the framebuffer address so the picture gets centered.

Fuzz tests ========== make run (with afl-fuzz installed) takes a real long time and creates test cases in jpeg-results/ that crash the jpeg code. These test cases can then be used to gdb the test app and dig into the decoder to fix the issues. This is mostly a proof of concept because the jpeg code isn't used very often (only for splash screens). However there are other regions in coreboot that could benefit from similar treatment.
