Adds pre-multiplication overflow detection to catch cases where dimension products would exceed size_t max. The previous check only detected when overflow resulted in exactly 0 or SIZE_MAX, missing other cases. Retains the original post-multiplication check for backward compatibility. Adds tests verifying overflow detection with dimensions (2^32+1)×(2^32), which previously overflowed silently to 2^32. This prevents custom SAX handlers from receiving incorrect array sizes that could lead to buffer overflows. Signed-off-by: Ville Vesilehto <ville@vesilehto.fi>
