  Pull request #1063: CAS-14797
  Merge in CASA/casa6 from CAS-14797 to master
  
  * commit 'd0332c4e3cda643f0a1b8a128c35f1a6ee2e973f':
    Streamline the implementations of helper functions in just two helper functions now made available in MatrixCleaner.cc
    Search only over inner square
    Make MSMT-CLEAN compatible with previous runs again
    repeat same accelerations for AspMatrixCleaner and for MultiTermMatrixCleaner
    This code will increase the speed for MS-CLEAN. This is achieved by two main improvements: -> Subtract beam is faster than casacore functionality which creates temporary copies -> Run peak finding only over square determined by blcdirty and trcdirty rather than the full image -> again, the direct implementation is faster than casacore minMax functionality

  This code will increase the speed for MS-CLEAN. This is achieved by two main improvements: -> Subtract beam is faster than casacore functionality which creates temporary copies -> Run peak finding only over square determined by blcdirty and trcdirty rather than the full image -> again, the direct implementation is faster than casacore minMax functionality
  For cygnus A, the upspeed in the minor loop was almost an order of magnitude.
  
  TBD: Apply the same to other deconvolvers.
