Added white hex outline on hovering round counter.

This fixes issue #2240

Note: As of now I am calling the displayVisualState() function everytime for each hex in the grid, everytime showGrid()is called. I didn't notice much of a performance difference but I've put the results in the comments related to this issue.

This is what it looks like after adding the white hex.

@dheerajd5 Heya! By "white outline" I didn't mean a new white hexagon (they tend to get edges overlapped at times), but css text effect for the letter-number coordinate, kinda like in this tut over here -> https://kinsta.com/blog/css-text-outline
