Hello I added the ability to change the background color I want

[pikachu987]

I needed to change the background color so I added a method to change the background color and the color of the Label

CircularSpinner.setBackgroundColor(UIColor.black)
CircularSpinner.setLabelColor(UIColor.green)

open class func setLabelColor(_ color: UIColor){
        let spinner = CircularSpinner.sharedInstance
        spinner.titleLabel.textColor = color
   }
    
 open class func setBackgroundColor(_ color: UIColor){
        let spinner = CircularSpinner.sharedInstance
        spinner.mainView.backgroundColor = color
  }
