A lot of features

[edenfisher]

Added lots of features , essentially useful for me but I believe would be useful for a lot of other people too.
Main Feature list and explanation:

• indicatorSizeRelativeToIcon - makes the small indicator under the tab, in the same size as the icon.
• widthPercentages - an array with the size relations between the tabs(if not set, would work like before.Including validation for values here).
• highlightedBackgroundColor - the background color of the highlighted tab.
• Theres a ESTabBarDelegate with the function tabClickedTwice which indicates the tab was
  clicked while it was already selected.(You might need to use the @objc annotation to use it)
• setIconImageAtIndex - ability to dynamically change the tabs icon

Thank you and pm if you do not understand anything

Any idea why there's a fail here?
