Add software gold generation for sparse to dense and dense to sparse conversion.
Fix bug in map.c where the flush signal for tiles residing in columns larger than 16 are not configured
Workaround for the currently broken dense scanner. This is done by setting the "opal_dense_scanner_workaround" flag in the deisng_meta.json file. If this flag is set, the flush signal is configured to be from a unused GLB tile.
