prevent cython.compiled raise AttributeError if cython not properly installed 
It's possible sometimes that 'import cython' does not fail but then 'cython.compiled' raises AttributeError.
It actually happened in our internal production environment...

Similar issue to https://github.com/pydantic/pydantic/pull/573 and https://github.com/ipython/ipython/issues/13294

Use Vector in some places where it improves the clarity of the code (#2206) 
* Use Vector in some places where it improves the clarity of the code

* add __all__ to vector.py

* turned some list comprehensions into generator expressions: there's no need for an intermediate list in these cases

* Add empty __slots__ to Vector, so we don't waste space on a __dict__.

* add some tests for segmentPointAtT
