Externalize KeyStore usage

[typelogic]

Current Behaviour

The current KeyStore usage only works on Java but not on Android due to differences in they way of securing keys. It raises the minSdkversion to 26, but is not used in Android.

Expected Behaviour

minSdkVersion version should be 16 and the handling of key security is outside the scope of ID PASS Lite reader and should be externalized.

Steps to Reproduce the Problem

1. Reader should not be responsible for key security. For example, this method should be externalized.

Context

N/A

• Version: 0.1
• Platform: Java, Android

Current findings:

• Not only is the KeyStore holding the 26 but also java.nio.file.Path in IDPassLoader.java
• Target min is 16 as it is default at AndroidStudio project creation
• Os.setenv() needs 21 but i think i can workaround this via JNI
