Refuse a fit=outside size whose output exceeds the maximum (closes #257)

fit=outside scales the source to cover the requested size, and the side scaled past it was held to no maximum: 1x8192?fit=outside of a 3000x600 source was resized to 40960x8192 and encoded. resize now refuses such an output with ErrOutputTooLarge before resizing, so both image routes answer it 400 with the error a size with one side 0 already gets. The other fit modes make the requested size or one within it. README.md and TODO.md say so. Model: opus-5-5
