BUG: Messy print statements

[fletchapin]

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of wwtp_configuration.

---

Description

I tried to set up intelligent __repr__() functions in every class, but the new lines are not organized well. As a result, the print statements using the package are very messy.

Expected Behavior

The print statement should represent the cleanest possible text equivalent of the configuration graph.

Reproduction

>>> json_path= tests/data/node.json
>>> print(JSONParser(json_path).initialize_network())

Environment

Ubuntu 20.04 with latest version of wwtp-configuration

As a part of this work, let's also make sure all fields are printed. E.g. Cogenerator doesn't print the attribute energy_efficiency
