Readme: Add More Precise Description for Weak or improper cryptography use

[LordAmit]

Hi,

When analyzing apk/java files, we noticed that QARK did not raise the alert about insecure parameters.

Cipher.getInstance(“des”);

Reporting this since in your readme you mention that “Weak or improper cryptography use” is attempted to be found.

Using QARK version 4.0.0 Using Python version 3.5.2 Using OpenJDK version 1.8.0_232 64 bit Running on Ubuntu: 18.04 Kernel: 4.4.0-174-generic
