  1. Add sub-pixel corner detection capability

    Introduces the function imcorner_subpixel as well as several requisite
    support functions to facilitate the ability to detect corners to
    sub-pixel precision.
    
    The imcorner_subpixel uses the existing imcorner functionality to obtain
    initial corner response values and a binary corner indicator matrix. The
    corner response values and the indicator matrix are used in a univariate
    quadratic interpolation scheme to determine the corner coordinates to
    sub-pixel precision.
    
    The new imcorner_subpixel function returns a length-3 NTuple of type
    HomogeneousPoint, which represents the homogeneous coordinates of a
    planar point.
