copyright header of zen/argon2.cpp

[daviank]

Hello,

In 12.0 there are two new files: zen/argon2.cpp & zen/argon2.h

While you are a copyright holder for argon2.h, you are not mentioned at all in argon2.cpp although you made changes there. You actually reference putty copyright holder only.

Can you confirm that the copyright header is as expected in argon2.cpp?

Thank you

[Zenju]

Fixed!
