ImageMagick has Division-by-Zero in YUV sampling factor validation, which leads to crash

A logic error in YUV sampling factor validation allows an invalid sampling factor to bypass checks and trigger a division-by-zero during image loading, resulting in a reliable denial-of-service. ``` coders/yuv.c:210:47: runtime error: division by zero AddressSanitizer:DEADLYSIGNAL ================================================================= ==3543373==ERROR: AddressSanitizer: UNKNOWN SIGNAL on unknown address 0x000000000000 (pc 0x55deeb4d723c bp 0x7fffc28d34d0 sp 0x7fffc28d3320 T0) #0 0x55deeb4d723c in ReadYUVImage coders/yuv.c:210 #1 0x55deeb751dff in ReadImage MagickCore/constitute.c:743 #2 0x55deeb756374 in ReadImages MagickCore/constitute.c:1082 #3 0x55deec682375 in CLINoImageOperator MagickWand/operation.c:4959 #4 0x55deec6887ed in CLIOption MagickWand/operation.c:5473 #5 0x55deec32843b in ProcessCommandOptions MagickWand/magick-cli.c:653 #6 0x55deec32b99b in MagickImageCommand MagickWand/magick-cli.c:1392 #7 0x55deec324d58 in MagickCommandGenesis MagickWand/magick-cli.c:177 #8 0x55deead82519 in MagickMain utilities/magick.c:162 #9 0x55deead828be in main utilities/magick.c:193 #10 0x7fb90807fd8f in __libc_start_call_main ../sysdeps/nptl/libc_start_call_main.h:58 #11 0x7fb90807fe3f in __libc_start_main_impl ../csu/libc-start.c:392 #12 0x55deead81974 in _start (/data/ylwang/LargeScan/targets/ImageMagick/utilities/magick+0x22fb974) AddressSanitizer can not provide additional info.
