Please add cl-one-time-passwords

It's lives here https://github.com/bhyde/cl-one-time-passwords, and this is it's system file: https://github.com/bhyde/cl-one-time-passwords/blob/master/cl-otp.asd

Previwe of README.md:
"One time passwords provide a way to do authentication based on a shared secret without revealing that secret on the communciation channel.

Two well specified ways of generating OTPs are:

• HOTP - An HMAC-Based One-Time Password Algorithm, i.e. RFC 4226
• TOTP - Time-Based One-Time Password Algorithm , i.e. RFC 6238

These are commonly used as one factor in two factor authentication systems. For example Google uses these. For example Google's Authenticator App for most smart phones will generate one time passwords once it has been configured with the shared secret(s) for your account(s).

Cl-one-time-passwords implements HOTP and TOTP in Common Lisp. ..."

Note: This was called cl-otp, but now it's called cl-one-time-passwords. Hopefully, the issue's text has been changed to reflect that.

Your defpackage forms don't include a :use clause - on SBCL that means that the CL package is not used, and that causes compilation failure when looking for functions named e.g. CL-HOTP::MAKE-ARRAY.

Thanks, I've mindlessly pushed a fix.

[quicklisp]

The package fix looks good, but SBCL now complains about clobbering literal data in HMAC-SHA-N. You want me to open up a separate issue for that?

[bhyde]

"clobbering literal data" has been addressed.
