Change Inset between checked Image and step circle

[OuSS-90]

Hello, Thanks for this awesome pod to make progressStep easier
I have one suggestion, is possible to have public var to change inset between checked Image and circle

Now by default it's 8 in UIImage+UIColor.swift:

func draw(inside rect: CGRect) {
      let insideRect = rect.insetBy(dx: 8, dy: 8)
      self.draw(in: insideRect)
 }

Cause I have image with white background color and i want it to take all circle like this:

Or is there a way to change checked background color to white ??
