v3.8.0

• introduced ability to create minimum-size AAR
  • a separate static library distribution now exists which contains a script that you can configure with features you need and it creates a AAR file which only contains features you need - this includes minimum-size native binary and only required assets. The rest (resources and java classes) can be thrown-away by ProGuard.
• LibBlinkID is now fully ProGuard-compatible, i.e. you no longer need to exclude com.microblink.** classes in your ProGuard configuration
• removed support for Android 2.3 and Android 4.0 - minimum required Android version is now Android 4.1 (API level 16)
  • devices with Android 4.0 and earlier take less than 2% of market share and is very costly to support them
• removed isItalic and isBold getters from OcrChar class
  • they always returned false, since OCR engine cannot accurately detect that
• removed setLineGroupingEnabled and isLineGroupingEnabled from BlinkOCREngineOptions because disabling line grouping completely destroyed the OCR accuracy
• added GermanIDCombinedRecognizer: scans front and back side of the German ID
