Support for EtM MAC Algorithms in FTP Server

One of the use cases we have for Cerberus FTP Server is to act as a repository for software images on networking equipment. The biggest vendors however, only have support for hmac-sha2-256-etm or hmac-sha2-512-etm MAC algorithms by default, which is unsupported by FTP server.

Please consider adding these as options to the application.
