add privacy manifest as per apple's new guidelines

[lakshmankreditbee]

Added app privacy file for File Timestamp API.
These are the list of APIs that require reason:
creationDate
modificationDate
stat
lstat(_:_:)

Given the reason as C617.1: Inside app or group container, per documentation

Quoting from Apple's documentation,

C617.1
Declare this reason to access the timestamps of files inside the app container, app group container, or the app’s CloudKit container.

We'll need to include this manifest in SwiftPackageManager (Package.swift) and/or CocoaPods (SSZipArchive.podspec), no?

Apologies for the oversight, yes we need to include this SwiftPackageManager (Package.swift) and CocoaPods (SSZipArchive.podspec)

Thanks for this work @lakshmankreditbee. Reviewing now. Seems simple enough. Running some tests and I'll get this merged in so everyone can benefit.
