public static boolean[][] upscale(boolean[][] compactShare)
```
    Uses designated diagonal patterns to extend raw entropy false and true values. It can be seen as the transformation from a compact share (not usable for visual cryptography) to a visual share (usable for visual cryptography)
    False (False) becomes: FT/TF.
    True (White) becomes TF/FT.
    
    Parameters:
    
    compactShare - as a share in its compressed state i.e. not yet visually perceivable.
    
    Returns:
    
    a visual share of double the dimensions where every position is boosted to a pattern.
