Update README.md

- Can change the command line SEMAG for graphs, SEMAC for classification.... and SEMAFL for federated learning?
- I think should not mention default families here. We can mention that in our provided model such as our model is trained on the dataset of these families...
- Some arguments are not necessary in DL. So I suggest to remove them.
- nparts argument? what do you use it for? I think we use a specific training folder in client's argument instead of using nparts.
- I think it's not necessary to show screen command here, but can use it in the example.

Merge branch 'production' into development-federated-learning
