Implement ARGON2 hash

#1150

@ljacqu we are only missing the test class i think

Looks good so far but it doesn't work yet ;) A hash will never be checked against its password successfully; you need to override comparePassword so it goes over the Argon2 class.

You can generate the test class for Argon2 by using AbstractEncryptionMethodTest#generateTest

How? XD

[ljacqu]

     /** Generates a test class for a given encryption method. Simply create a test class and run the following code,
     * replacing {@code XXX} with the actual class:
     * <p>
     * <code>@org.junit.Test public void generate() { AbstractEncryptionMethodTest.generateTest(new XXX()); }</code>
     * <p>
     * The output is the entire test class. */

So just create an Argon2Test class, and in it have the code posted above and you're good to go ;)

Edit: i.e.,

• create Argon2Test class
• paste inside class: @org.junit.Test public void generate() { AbstractEncryptionMethodTest.generateTest(new Argon2()); }
• run test, copy output
• replace Argon2Test class with the copied output
• run test again 😄

Test is failing, any idea?

Hopefully fixed it. Reason is the test was confused because Argon2 extends UnsaltedMethod but it's very much salted—we just don't have to worry about it ourselves.
