IO Freeze for EnergyPlus, Version 22.1.0

Unless something goes awry, this is the IO freeze point for version 22.1.

Version 9.5 with Python 3.8, Take 3

Internal build. Please do not delete (@bonnema).

Version 9.4 with Python 3.8 for Windows 32-bit, Take 6

Internal build. Please do not delete (@bonnema).

Special build of 9.6 with EPW fix

This is just the v9.6.0 tag but with the commits of #9216 cherry picked. This build will likely be deleted once we are done with it.

EnergyPlus 9.6.0 Plus Space-related Fixes

A special release of EnergyPlus 9.6 that includes some critical fixes related to the new space concept. This is going to be an officially supported release, but it will be marked as pre-release and not highly advertised because users generally should just use the original v9.6.0 release.

If this release is good to go, I'll update this comment with additional information. If more changes are needed then I'll delete this release after everything settles down.

EnergyPlus 9.6.0 IO Freeze

OK, I believe this is the IO freeze version of EnergyPlus. All the pull request labeled for the IO freeze milestone have been merged in. There are definitely still plenty of things to do before release happens, but that's what the post-IO-freeze period is all about. Barring something crazy, this is the IO freeze release.

Custom Installer #4 for OpenStudio with HVAC Flex Measures

The QtIFW stuff has been resolved in develop. Those workflows are now properly pulled into this branch. The HVACFlexMeasures branch is still quite a ways behind develop, so there is a chance that something is not compatible. But let's see what happens.

Custom Installer #3 for OpenStudio with HVAC Flex Measures

Got the QtIFW stuff fixed on develop, so I pulled the workflow rules into this branch. If it fails to build, it's because some other change has been made in the workflows that is causing a conflicted build state. If that happens, I will make one pass to revert all the workflow changes that have been made here and then just tweak the Qt stuff to fix what I just fixed in develop. If that doesn't work then, well, I'm done trying for now.
