Minor internal changes

Remove sizeToFit() from SizeCalculable protocol.
This change ensure that PinLayout pin.sizeToFit() method behave correctly. As per the iOS documentation, we should not directly override sizeToFit() but rather always only implement sizeThatFits(_:) for auto-sizing needs. This update aim to remove the sizeToFit() requirement in the SizeCalculable protocol.

Add methods to layout a view between two other views

Add methods to layout a view between two other views

Add methods to position a view between two other views, either horizontally or vertically.

New Methods:

• horizontallyBetween(:UIView, and: UIView)
  Position the view between the two specified views horizontally. The method layout the view's left and right edges. The order of the reference views is irrelevant.
  Note that the layout will be applied only if there is horizontal space between the specified views.

• horizontallyBetween(:UIView, and: UIView, aligned: VerticalAlign)
  Position the view between the two specified views horizontally and aligned it using the specified VerticalAlign. The view will be aligned related to the first specified reference view. Note that the layout will be applied only if there is horizontal space between the specified views.

• verticallyBetween(:UIView, and: UIView)
  Position the view between the two specified views vertically. The method layout the view's top and bottom edges. The order of the reference views is irrelevant. Note that the layout will be applied only if there is vertical space between the specified views.

• verticallyBetween(:UIView, and: UIView, aligned: HorizontalAlign)
  Position the view between the two specified views vertically and aligned it using the specified HorizontalAlign. The view will be aligned related to the first specified reference view. Note that the layout will be applied only if there is vertical space between the specified views.

Example:

   view.pin.verticallyBetween(viewA, and: viewB, aligned: .center).marginVertical(10)
