- Allow the use of enc_id == 0 in hash-mode 10600 and 10700 as it takes no part in the actual computation
- Get rid of exit() calls in OpenCL wrapper library with the goal to have a better control which error can be ignored under special circumstances
+- Do not error and exit if an OpenCL platform has no devices, just print a warning and continue with the next platform
