[pic2card] Stabilizing columns grouping

[Keerthana786]

• Reduced the number of thresholds used for column-set and columns grouping.
• Used horizontal and vertical inclusive logic to group the objects into a column-set or column.
• Changes in noise removal : along with the IOU based removal , the smaller objects [ in overlapping scenarios] which covers more than 50% of the intersection area will also be removed.
• Changed the columns and column-set alignment logic of doing max of count of the alignments to choose from a predefined order - Left, Center, Right in cases where the alignments of the objects are unique.
  • for example: if a column as 2 elements with ["Right", "Left"] as alignments, on doing max of count will pick different alignment each time, instead changed the logic to choose in the predefined order in case of unique alignments.
  • So if the alignments of the objects are ["Right", "Center"] in a column , then the column's alignment will be Center.
• Removed the redundant call made to get_objects method in debug API to one.
