More information for the `README.md`.

Not a big deal, but when using the library, it behaved wrongly(the input view was leaving too much space than it actually needed) because of the IQKeyboardManager library that I was using.

I had to add the view controller that I was using this library with to the ignore list of the IQKeyboardManager like following so:

IQKeyboardManager.shared.disabledDistanceHandlingClasses.append(ViewControllerType.self)

In my opinion, it would be great to mention this in the README.md file. It took a while for me to find out what was the issue :).
