Subject: [PATCH] rdppm.c: Fix buf overrun caused by bad binary PPM
This extends the fix in 1e81b0c3ea26f4ea8f56de05367469333de64a9f to
include binary PPM files with maximum values < 255, thus preventing a
malformed binary PPM input file with those specifications from
triggering an overrun of the rescale array and potentially crashing
cjpeg, TJBench, or any program that uses the tjLoadImage() function.
Fixes #433
