offsetToLocalFileHeader greater than 32-bit int limit throws exceptions

When parsing a large zip file with:
const archive = await unzipper.Open.file('some/file/path.zip');if a file's offsetToLocalFileHeader is greater than the 32-bit integer max value of 4,294,967,296, its value will end up being null and not a number:
archive.files.length;
// 28
archive.files.filter(file=>file.offsetToLocalFileHeader===null).length;
// 10which will throw an ERR_INVALID_ARG_TYPE exception when trying to get a stream to the file:
const stream = archive.files.at(-1).stream();System info:
- unzipper v0.12.1, but this issue has been present since at least as far back as v0.10.14
- Node.js v20.14.0
- TypeScript v5.4.5
- macOS M2 Sonoma v14.5
Here's an example zip file, this problem happens with central directory entries 19-28:
$ unzip -Zsvh "Amazing Spider-Man, The - Ultimate Edition (USA) (En,Fr,Es).zip"
Archive: Amazing Spider-Man, The - Ultimate Edition (USA) (En,Fr,Es).zip
The zipfile comment is 22 bytes long and contains the following text:
======================== zipfile comment begins ==========================
TORRENTZIPPED-FD9EB058
========================= zipfile comment ends ===========================
End-of-central-directory record:
-------------------------------
Zip archive file size: 9181844173 (000000022347D2CDh)
Actual end-cent-dir record offset: 9181844053 (000000022347D255h)
Expected end-cent-dir record offset: 9181844053 (000000022347D255h)
(based on the length of the central directory and its expected offset)
This zipfile constitutes the sole disk of a single-part archive; its
central directory contains 28 entries.
The central directory is 2159 (000000000000086Fh) bytes long,
and its (expected) offset in bytes from the beginning of the zipfile
is 9181841894 (000000022347C9E6h).

Hi there,
I was looking into it as I faced the same issue. Debugging my way through, I discovered that the problem lies with the extra field of Zip64. The current logic expects all fields to always be present in the Zip64 entry (which is not necessarily the case). I changed the logic to check which values should be present based on the values in the Zip64 central directory.
