Target, compile SDK, AGP and gradle versions increased

[somalaya]

• Target sdk version changed to 33
• Compile sdk version changed to 34
• AGP version changed to 7.4.2
• Gradle distribution url changed to 7.5

After changing above versions, I had to update other dependencies for compatibility

• Powerlift version changed to 1.0.3
• Bouncy castle version changed to 1.69
• robolectric version to 4.9
• Also, with new gradle versions, some of the properties used in gradle were deprecated (naming conventions changed). So, made those changes
• With gradle version changes, we should not be having a package name in AndroidManifest.xml.. instead, should add a namespace property in build.gradle. https://developer.android.com/build/publish-library/prep-lib-release#choose-namespace
• For apps targeting Android 14, Android restricts apps from sending implicit intents to internal app components. So , added exported attribute. https://developer.android.com/about/versions/14/behavior-changes-14#safer-intents
