The native library is loaded in the main thread, which generates an ANR

Description

We are experiencing ANR events when the license is set in the Application.onCreate callback. The ANR is triggered because the libBlinkID.so library is being loaded in the main thread. Please refer to the following stack trace for more details

Additional information

In addition to the bug, I would like to comment that we'd prefer not to initialize Microblink in the Application.onCreate callback. This is because Microblink is not used every time the app is opened; on the contrary, most of the time it is not used. Instead, we'd like to initialize Microblink only when we need it. Could you provide a way to initialize the library only when needed?
