Subject: [PATCH] set `srided_index = true` as default

Change the default for strided index. Th euser feedback shows that strided_index = true will give a view hashes more per second.

 ### Scratchpad Indexing
 
 The layout of the hash scratchpad memory can be changed for each GPU with the option `strided_index` in `amd.txt`.
