feat(isisVarInit.py): Removed the default "cat" in the written activation

## [Unreleased]

### Changed

- isisVarInit.py no longer writes a "cat" statement by default to the activate scripts which cause the ISIS version information to be written on conda activate.  This can be included in those scripts via a command line option to isisVarInit.py.  Also, a quiet option is provided to isisVarInit.py to suppress its own writing to standard out, if needed.

### Fixed

- Fixed logging in FindFeatures where we were trying to get a non-existent Pvl group from the Pvl log. [#4375](https://github.com/USGS-Astrogeology/ISIS3/issues/4375)

- Fixed an arccos evaluating a double close to either 1, -1 when calculating the ground azimuth in camera.cpp. [#4393](https://github.com/USGS-Astrogeology/ISIS3/issues/4393)

removed at deactivation.

If the directories don't exist, they are created.  If their path is

not specified, they are placed in $ISISROOT.
