project_euler/problem_47/sol1.py (#2150)
* Create __init__.py

* Initial commit

Not sure if this should be formatted differently.  I'm open to ideas!

* Completing testing/updates

Ran code through `black`, `flake8`, and `doctest`.  Added some type hints.

`doctest` is finicky on sets, so I had to sort and reformat as set to pass those tests.

* Update project_euler/problem_47/sol1.py

Nice.
