fix: issue #86, swap from strconv.Atoi to strconv.ParseInt(parts[1], …

…10, 64) (#87)

This change solves a problem on 32-bit systems where file sizes larger than 2^32 could not be parsed. By using ParseInt directly and setting the bit-size to 64 explicitly, the size is always parsed and stored as a 64-bit integer regardless of the host platform.
