[question] File too large error when file is exactly the size of fileSize

I would like to allow files up to and including 10mb (10,485,760 bytes) and have specified `fileSize` with this number of bytes. When I tried uploading a file exactly 10485760 bytes in size, I received the "File too large" error. If I increase `fileSize` by 1 byte then I can upload the file.

Should I specify `fileSize` with a number 1 byte large than my intended maximum allowed file size?

Multer verson:
`"multer": "^1.4.5-lts.1"`

Code:
```
const storage = multer.memoryStorage();
const maxSize = 10 * 1024 * 1024; // 10MB
const upload = multer({ storage, limits: { fileSize: maxSize } }).any();
...
upload(req, res, (err) => {
if (err) {
logger.error(`${err?.message ? err?.message : err}`);
}
...
}
```
