Refactor sierpinski_triangle.py ()
* updating DIRECTORY.md

* Update sierpinski_triangle.py header doc

* Remove unused PROGNAME var in sierpinski_triangle.py

The PROGNAME var was used to print an image description in the reference
code that this implementation was taken from, but it's entirely unused
here

* Refactor triangle() function to not use list of vertices

Since the number of vertices is always fixed at 3, there's no need to
pass in the vertices as a list, and it's clearer to give the vertices
distinct names rather than index them from the list

* Refactor sierpinski_triangle.py to use tuples

Tuples make more sense than lists for storing coordinate pairs

* Flip if-statement condition in sierpinski_triangle.py to avoid nesting

* Add type hints to sierpinski_triangle.py

* Add doctests to sierpinski_triangle.py

* Fix return types in doctests

* Update fractals/sierpinski_triangle.py

Refactor local_weighted_learning.py to use np.array ()
* updating DIRECTORY.md

* Format local_weighted_learning.py doctests for clarity

* Refactor local_weighted_learning.py to use np.array instead of np.mat

The np.matrix class is planned to be eventually depreciated in favor of
np.array, and current use of the class raises warnings in pytest

* Update local_weighted_learning.py documentation
