RenderNodeBlurController does not use `DEFAULT_BLUR_RADIUS`

[nikclayton]

Please include:

1. Library version: "com.github.Dimezis:BlurView:version-3.2.0"

In BlurViewFacade.setBlurRadius, the default value is noted:

BlurView/library/src/main/java/eightbitlab/com/blurview/BlurViewFacade.java

Lines 34 to 39 in fbd355b

	/**
	* @param radius sets the blur radius. The real blur radius is radius * scaleFactor.
	* Default value is {@link BlurController#DEFAULT_BLUR_RADIUS}
	* @return {@link BlurViewFacade}
	*/
	BlurViewFacade setBlurRadius(float radius);

and is defined in

BlurView/library/src/main/java/eightbitlab/com/blurview/BlurController.java

Line 8 in fbd355b

float DEFAULT_BLUR_RADIUS = 16f;

However, in RenderNodeBlurController.java it is not used, instead it is set to 1f

BlurView/library/src/main/java/eightbitlab/com/blurview/RenderNodeBlurController.java

Line 34 in fbd355b

private float blurRadius = 1f;

So

binding.blurView.setupWith(binding.blurTarget)
    .setBlurRadius(BlurController.DEFAULT_BLUR_RADIUS)

gives a very different result to

binding.blurView.setupWith(binding.blurTarget)

on systems where RenderNodeBlurController is used (i.e., where hardware rendering is available).

Fixing this to use the same default in both should probably be considered a breaking change in the library, warranting a major version bump, as it will cause the externally-visible default behaviour to change.
