Train cloud microphysics

This is the first release that contains an app/train_cloud_microphysics.f90 program and a training_configuration.json file that exhibits convergent behavior of the (Adam) training algorithm on an ICAR-generated training data set by as demonstrated by a monotonically decreasing cost function:

    ./build/run-fpm.sh run train-cloud-microphysics -- --base training --epochs 10 --start 720
    ...
