Added support for multiple lines title text

[Satish24sp]

Added support for multiple lines title text with swipe menu segment style so that we can overcome the issue of text truncation.

Support has been added in the below classes:

1. SwipeMenuView.swift at L38 to L41 Added new public parameter in a function i.e. public struct ItemView {....} After:

 /// ItemView title number of lines . Defaults to `1`.
      public var numberOfLines: Int = 1

2. TabView.swift at L218 to L224. Modified the existing function i.e. fileprivate func setupTabItemViews(dataSource: TabViewDataSource) {....} Before:

if let title = dataSource.tabView(self, titleForItemAt: index) {
   tabItemView.titleLabel.text = title
   tabItemView.titleLabel.font = options.itemView.font
   tabItemView.textColor = options.itemView.textColor
   tabItemView.selectedTextColor = options.itemView.selectedTextColor
}

After:

if let title = dataSource.tabView(self, titleForItemAt: index) {
   let itemView = options.itemView
                
   tabItemView.titleLabel.text = title
   tabItemView.titleLabel.numberOfLines = itemView.numberOfLines      // Change for multiple lines
   tabItemView.titleLabel.font = itemView.font
   tabItemView.textColor = itemView.textColor
   tabItemView.selectedTextColor = itemView.selectedTextColor
}

Final Result:
