Avoid new implicit float to int conversion warnings in Python 3.8

Fix show detectors in workbench with Python 3

Python 3.8 deprecates implicit conversion from float->int and
warns on it. We simply force the conversion explicitly
Refs #27717

In Python 3 map returns a generator and these cannot currently
be passed over the C++ boundary.

Fix issues with workbench plotting with matplotlib 3.1

It has been deprecated in matplotlib for a long time
and is removed in 3.0. Callers should clear the axes
themselves if thay is appropriate.

The API changed in matplotlib 3.1 but we still need to support
matplotlib > 1.5.

Some configurations now have the sip module inside
the PyQt package. To access the sip C API the
calling code must be aware of this.
All versions of Python that we support have capsule
support so the non-capule code paths have been removed

Python 2 does not have this DLL.

As far as I can tell these were leftover attributes from
a very old version of the matplotlib NavigationToolbarQT
class that have now been deprecated in matplotlib 3.1 and
set as readonly. A search back through matplotlib 1.5
suggests that they were not used and 1.5 is the minimum we
are required to support.

Users cannot do anything about this as they are not using
the methods directly. If they use them they will see
the warning but we do not want to see them if we are silently
accessing them.

Fine also on macOS. Nice feature!

Update macOS package script to account for Python 3 requirements

Cosmetic changes to directtools plot on Workbench

Remove the dead tool code DAEServ

Mainly this is due to more recent package versions on Python 3 to their
requirements are different.

exposed rebinned output to python and fix load save as nxs (no ticket)

Disable show instrument if there is no spectra axis
