The CDS conda environment has been updated.

If you run in to trouble with the new environment, you can switch back to the production environment with 'conda activate cds-py310-2023120401'

This environment includes two new programs from Gabriele: 'interactivefitting' and 'loopdesigner'.

It also includes a new release of diaggui and foton, version 4.0.3.  This version has minor improvements and bug fixes.

foton now can suppress warnings for zeros in the right-hand plane.  Pass -Z f as a command line argument or set the environment variable FOTON_WARN_RHP_ZEROS=false.  The environment variable will also work with python-foton.

Difference cursors now work in diaggui plots.
