- Remove modified background color -> should be discusses as a separate feature
- Render shields as thin tinned wire with black border, safer for b&w priting than single light-gray line
- Remove PE as color definition, since it is not, and should be called with GNYE
- Clean up minor things
* Format all files using autopep8 to add basic PEP8 conformity.
* Add Exception types to bare excepts to prevent catching `ctrl+c`
* Remove some unnecessary assignment to dummy variables before returning
* Add `Optional` to type hints that can be `NoneType`
* Change a number of single-letter variables to more descriptive names
* Replace string.format() use with Python's f-strings, as they tends to be cleaner, and provide a performance boost.
* One multiline string was left as string.format() as I do not believe f-strings support multiline
* Some of the string.format() instances had unused/ignored arguments. I left them out of the f-strings, but I marked those cases with a comments that begins `# FIXME:`
* Rename variables that were shadowding python standard functions (specifically `format->fmt`, `input->inp`, `type->maintype`)
* Some instances of `type` were not changed, as it breaks the yaml parsing. Needs to be looked into.
* Move classes in `wireviz.py` to two new files `DataClasses.py` and `Harness.py`.
