hashcat/OpenCL/m13400.cl
jsteube 33a043ec63 Refactored internal use of esalt from sync with number of salts to sync with number of digests 
This enables a true N esalts per salt feature which is required for WPA/WPA2 handling
In case we need that for a future algorithm, just make sure to have a unique value in digest in hash parser.
Fixes https://github.com/hashcat/hashcat/issues/1158
