Increase cooling-off period (Issue #200) Changed the value of SSR_I_CAL_MAX_CONTINUOUS_CURR from 6.75 to 4.

Change "SSR" to "SSR/FET" in UI (Issue #199) All user-visible references to SSR now also mention FET. Some, but not all of the internal names have also been changed.

Update DMG_background.jpg Updated the last step of the instructions for newer MacOS releases. Also changed "Right-click" to "Control-click" in second step.

Explicitly specify PDF backend for matplotlib Pyinstaller 5+ (thankfully) no longer defaults to loading all matplotlib backends. But for it to auto-detect the backend that we need, it has to be explicitly called out in the Python code. This change imports the matplotlib "use" function and calls it with "pdf". See https://pyinstaller.org/en/v5.0/hooks-config.html#matplotlib-hooks

Another update to build_tools README Removed the pyinstaller workaround for the msgcat bug since it is no longer necessary

Update build_tools README Removed instructions for modifying the pyinstaller hooks. It is no longer relevant.

Update python3 README Fixed a couple things in the README: - Removed bash profile setup for pyenv and replaced with pointer to instructions for all shells in pyenv repo - Removed tcl/tk options from pyenv install command line since they are no longer needed

Log the ZMQ version Added the PyZMQ version to the log file (no Issue filed)

Update build_tools README All mention of Python 2 builds have been removed. The pyinstaller script command lines have the "python3" argument removed because the scripts no longer require an arg. The path to the Mac pyinstaller hooks folder is updated. A (Mac) step is added to apply a generic code signature. This is required for the downloaded app to be installed on newer MacOS versions without an actual code signature. [However, I don't even know if this works for versions newer than Monterey] Added some additional acceptable warnings for Mac build.

Remove support for python 2 Since Python 3 support was introduced, the mac_run_pyi and run_pyi.bat scripts required an argument of "python" or "python3". Now Python 2 is no longer supported, so the scripts are simplified to assume python3.
