    Fixed another issue with invalid DICOM images.

    Fixed issue when processing an invalid DICOM image where the number of
    pixels stored does not match the expected number of pixels (too less)
    and the combination of BitsAllocated and BitsStored is really unusual
    (e.g. 1 bit stored, but 52 bits allocated). In cases where the last
    pixel (e.g. a single bit) does not fit into the buffer of the input
    pixel data, a buffer overflow occurred on the heap. Now, the last entry
    of the buffer is filled with the smallest possible value (e.g. 0 in case
    of unsigned data).

    Thanks to Ding zhengzheng <xiaozheng.ding399@gmail.com> for the report
    and the sample file (PoC).
