v1.9

• Added support for NSProgress and NSProgressReporting in all extraction and iteration methods (Issue #32)
• Added detailed logging using new unified logging framework. See the readme for more details (Issue #47)
• Added support for archiving and restoring files' POSIX permissions (PRs #84, #86, #87 - Thanks, @MartinLau7!)
• Added methods to check data integrity of an individual archived file, or the entire archive (Issue #63)
• Fixed a crasher in extractBufferedDataFromFile:error:action:, which also manifested in other methods that use it, like validatePassword (Issue #51 - Thanks, @amosavian, @monobono, and @segunlee!)
• Upgraded project to Xcode 9 and to the macOS 10.13 and iOS 11 SDKs (Issue #61)
• Consolidated targets so they're shared between iOS and macOS (Issue #62)
• Added a CocoaPods test spec (Issue #59)
• Improved the way warnings are ignored to be more consistent, and so they're only ignored in minizip, and not the UnzipKit sources (Issue #68)
