[Ach] OpenSSH: aes192-crt

Hey there,

while we reviewed the OpenSSH section in
  https://github.com/BetterCrypto/Applied-Crypto-Hardening/pull/32/files

we realized the list of Ciphers could be extended by "aes192-ctr" to

> Ciphers aes256-gcm at openssh.com,aes128-gcm at openssh.com,
>         aes256-ctr,aes192-ctr,aes128-ctr
_________________________|

The extension by that "intermediate" bit strength looks trivial and
compatibility-widening at the beginning, but we were not sure if it is
actually "save" (because the other sections in the document only use 128
and 256).

Does someone have more knowledge about that?

Cheers,
Axel
