Config builder subclasses have redundant methods.

[bauerfe]

          I just double-checked that all the other classes are not changing the parent's behavior class.

To be precise:
The other classes add a:

config_dict.pop("weights_kill_bit")
config_dict.pop("biases_kill_bit")
config_dict.pop("neurons_value_kill_bit")

However, in the parent class, we find:

# config_dict["weights_kill_bit"] = torch.zeros_like(weights).bool().tolist()
# config_dict["biases_kill_bit"] = torch.zeros_like(biases).bool().tolist()
# "neurons_value_kill_bit" : torch.zeros_like(neurons_state).bool().tolist()

these entries will only be generated/updated when calling set_kill_bits.
