Prepare a DigitalDLSorter object that has a
DigitalDLSorterDNN object with a trained DNN model.
keras models cannot be stored natively as R objects (e.g. RData or RDS
files). By saving the structure as a JSON-like character object and the
weights as a list, it is possible to retrieve the model and make predictions.
Note: with this option, the state of optimizer is not saved, only
the architecture and weights.

A DigitalDLSorter or
DigitalDLSorterDNN object with its trained keras model
transformed from a keras.engine.sequential.Sequential class into a
list with the architecture as a JSON-like character object and the
weights as a list.
It is possible to save the entire model as an HDF5 file with the
saveTrainedModelAsH5 function and to load it into a
DigitalDLSorter object with the
loadTrainedModelFromH5 function.
It is also possible to save a DigitalDLSorter object as
an RDS file with the saveRDS function without any preparation.
