each layer, required for clustering; related updates
update class ThermalAnalyzer, added pointer to thermal_map of (previous) thermal-analysis
iteration; related updates class FloorPlanner
update class ThermalAnalyzer, extended thermal map w/ structure ThermalMapBin; related
updates
added ThermalAnalyzer::initThermalMap, used to init thermal map w/ ThermalMapBin 2D array,
      and to determine neigbor relations in 2D array; related update/fix

      FloorPlanner::initThermalAnalyzer
major update FloorPlanner::clusterSignalTSVs; related updates/fixes
minor fix FloorPlanner::clusterSignalTSVs, reset hotspot regions for each run
update IO::writePowerThermalTSVMaps, added plotting of hotspot clusters
fix FloorPlanner::evaluateLayout, re-determine hotspot cluster and TSV island for the
finalization run w/ best solution

minor update FloorPlanner::clusterSignalTSVs, update comments and dbg
update FloorPlanner::clusterSignalTSVs, added reset for bin-hotspot associations, update
dbg; related update ThermalAnalyzer::performPowerBlurring
update IO::writePowerThermalTSVMaps, also consider background and undefined hotspot
regions bins for output
update/fix FloorPlanner::clusterSignalTSVs, post-process hotspot regions such that also
regions marked as still growing after blob detection are appropriately evaluated
