This refactor changes the structure of Visibilities objects from a 2D NumPy array of floats of shape [total_visibilities, 2] to a 1D complex NumPy array of shape [total_visibilities].

This is the format that PyNUFFT uses to represented the data, minimizing uncessary data conversions that cause slow down the code for large visibilitiy datasets.
