Bug Fix

• Fix GridTiler's _are_coordinates_within_extraction_mask method where tile coordinates are off by 1 or 2 pixels due to conversion of floats to ints. (#308)
• Fix the mismatch between row-column / X-Y coordinates in the RandomTiler (#317)
• Fix return type of RGB to LAB filter. (#323)
• Filter kmeans_segmentation is now applied only to RGB images. (#328)
