Remove groups of NaN and leave a single separator.
For any number of vectors, x, y, z, …, reduce groups of contiguous NaNs into a single NaN separator. The vectors must all have the same dimensions and the NaNs must be locations. Leading NaNs are removed, and trailing NaNs are reduced to one.
removeExtraNanSeparators ([NaN NaN 3 4 5 NaN NaN 8 NaN], [NaN NaN 7 6 5 NaN NaN 2 NaN]) ⇒ [3 4 5 NaN 8 NaN] ⇒ [7 6 5 NaN 2 NaN]
