--- THIS IS COMBINING TWO COMMITS ---

Bumped normalizing functions out of a class as the class was not helping to
make the code any more readable.

Each of the normalizing functions are now their own separate function, found
after the `LoadResults` class.

It'd be best practice to put those functions inside a module, but I don't
think doing that would fit within the scope of this project.

---

Other changes include removing the `name-slug` RawResult attribute, returning
"more raw" name data from the files (i.e. using `family_name` and `given_name`
instead of merging the two into `full_name`).

Removing `cls` argument from normalizing functions...
