Prevent an overflow when locating a pack's CRC offset when the number of packed items is greater than 2^32-1/hashsz by guarding the computation with an `st_mult()`. Note that to avoid truncating the result, the `crc_offset` member must itself become a `size_t`. The only usage of this variable (besides the assignment in `load_idx()`) is in `read_v2_anomalous_offsets()` in the index-pack code. There we use the `crc_offset` as a pointer offset, so we are already equipped to handle the type change.
