Thanks very much, this is really useful. I split out the 1994 variant into a separate operation called 'GOST hash' as it's not really Streebog. It makes more sense to have separate operations for them.

Now that we have the full GOST library incorporated into CyberChef we should implement operations for the GOST block cipher as well. I'll raise an issue for it.
