Add support for AES Counter mode

Motivation:

AES in counter mode is not an uncommon primitive to see. While this isn't as good as an AEAD construction, there are some cases in which it is necessary to use this mode.

Modifications:

Add AES in CTR mode, behind an underscore.

Result:

Counter mode support is available.
