* Fix AWG<-> mm2 conversions
Add an inverted dictionary and a lookup function from awg -> mm2. Also
do some minor refactoring. Both sides of the conversion table were
converted to strings, since '0000' and '2/0' are perfectly valid AWG
values.
* Update example ex02 with awg -> mm2 conversion
Show conversions for ex02, and make sure it displays conversions in both
directions. Rebuild the example files.
* Fix faulty conversion of non-(mm2,AWG) units
The parsing allows arbitrary units to be used for cable dimensions --
this might be valid units, e.g. square inches, or invalid, e.g. bananas.
We only allow conversion between mm2 and AWG, so check that the
gauge_unit is either of those before conversion. If not, pass through as
is.
* Fix AWG string casing in output
Convert e.g. 'awg, 'AwG' to upper case for consistent rendering. Leave
any other input gauge units as they were.

* 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`.

- Allow prepending a separate YAML file for e.g. including common
template definitions. This is accomodated by a new commandline option,
--prepend-file, which takes a path to a YAML file. This is prepended
to the regular input as-is.
- Refactor file loading to accomodate the above. This includes moving
relevant parts to main() and instead supplying parse () with a string
representation of the YAML data. Also add early file existance checks
and bail out if any of the inputs are inaccessible or nonexistant.
There are hard copies of the graphviz and pyyaml dependencies included
in the repo. Remove these.
Sort out installation and dependency handling by writing a functional
setup.py script. Rename top level documentation. Refactor wireviz.py
slightly to allow it to run as an installed script.
