Add function to return english words

[fhightower]

WHAT I want this project to do (or not do)

I would like a function that returns a generator with every english word.

WHY I want this project to have this feature

Such a function would facilitate other functions.

HOW we might implement this feature

I image the function signature like:

def english_words() -> Iterable[str]:
    ...

This could be generalized to other languages like:

def words(language: str) -> Iterable[str]:
    ...

where language is some kind of language identifier.
