Vectorizedect

[yemeen]

rewrites ect class to use vectorized computations and defines ECTResult class to store ect_arrays with plotting capabilities. also adds n-dimensional support

Description

separates concerns from embeddedgraph class and ect class. adds a new directions class for precise direction handling.

ect class now uses directions matrix to project graph coordinates. numba prange is used to make things fast:

      "points_100000_complexity_5": {
        "mean_time": 0.7333681106567382,
        "std_time": 0.011764391608895074,
        "min_time": 0.7214951515197754,
        "max_time": 0.7503418922424316
      }

embeddedgraph now maintains a coord_matrix for easy retrieval.

Motivation and Context

allows for easier extension of code and faster run times.

How has this been tested?

added new tests to handle code structure
