For CAS-14763, added skeletal ZenithDelayJones class (ZenithDelayCal.{h,cc}) to eventually support application of zenith-angle dependent macroscopic delay calibration for VLBI, and make VisCalGlobals's SolvableVisCal factories aware of it. This requires further development for it to work.

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 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. -

Fix missing key error for flagged data
The cost function would try to index data that was none
existent because of the crappy handling of the reference
antenna list. It now avoids things for which there's no
dictionary entry.
Also, run black on the code. -

that had all their solutions flagged. -

Preliminary zenithdelaycal implementation
tl/dr: this needs more work; polarization, flags, antenna parsing.
Implements the scipy-based least squares solver for the
zenith delay. It only handles one polarization, it will likely
raise an exception if the antenna parameter is a string, and it
ignores flags in the multi band delay solutions. -
