Don Cross 2aa26aba78 Python: implemented VectorObserver function.

I already had the function ObserverVector that converts geographic
coordinates (latitude, longitude, elevation) to an equatorial-of-date
(EQD) vector.

Now I'm in the process of adding the inverse function VectorObserver
that calculates geographic coordinates from an EQD vector.
This commit implements VectorObserver in Python.
The other languages will follow in future commits.

The motivation was from the following request:
https://github.com/cosinekitty/geocalc/issues/1
The goal is to find the near-intersection between two different lines
of sight from two different observers on the Earth's surface.
Added a demo program triangulate.py that solves this problem.
