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.
