Adding Session Manager and Password Encryptor.

[theetherGit]

We usually rely on many libraries and I'm sure we going to use Legos in many projects. So, I was thinking of adding Session Manager based on Redis and Password Encryption method using crypto also being used in lucia-auth but they can provide password encryption method library but they won't so we can provide in legos.

What's do you say @ankurrsinghal on this?

If you want to i can add contribute for that.
