This feature brings SDL's TextInput feature into Ruby2D.
It adds the new TextInput class that inherits from Text and has the following attributes:

TextInput.new(
  'Hello',
  x: 150, y: 470,
  font: 'vera.ttf',
  style: 'bold',
  size: 20,
  color: 'blue',
  opacity: 1,
  rotate: 90,
  z: 10,
  show: true,
  maxlen: 20,
  maxwidth: 260,
  caret_color: 'red'
)

To enable input you call TextInput.focus to gain the focus and catch the keyboard. When you are done, call TextInput.unfocus to release the focus. You can also query the focus status by calling TextInput.focused?.
The entered text is available in TextInput.text.
TextInput is just a simple text field, it is not a text area and it handles the following special keys: 'left', 'right', 'home', 'end', 'backspace', 'delete'.
It is up to you to release the focus - for example when 'enter' or 'esc' are pressed or the mouse is clicked outside its area.
