Add privacy manifest

Apple's update to their API policy - Required Reason

Goals ⚽

To comply with Apple's new privacy policies every app and third-party SDK should include a Privacy manifest in case if they access APIs which potentially can be used for fingerprinting.
All use cases of such API require explicit reasons declaration.

FileKit wrapped creationDate and modificationDate which is included in a required reasons API.

Implementation Details 🚧

• Added a PrivacyInfo.xcprivacy file. The file requires all four fields
  to be included:
  • SDK does not use tracking;
• Tracking domains array is empty. It can be empty as long as tracking
  is false;
  • SDK does not collect any data. NSPrivacyCollectedDataTypes is empty;
• SDK uses creationDate, Reason: File Timestamp - 0A2A.1: 3rd-party SDK wrapper on-device, per documentation
• SDK uses modificationDate, Reason: File Timestamp - 0A2A.1: 3rd-party SDK wrapper on-device, per documentation
• Updated Package.swift file to include the privacy manifest to the SPM.
• Update FileKit.podspec file to include the privacy manifest to the Cocoapods
