Fix:revolving dot issue #140

This fixes Revolving dot issue #140

Both the circles are now scaling up and down properly without getting cropped.

Some additions

• Added support for secondary color
• Added support to change stroke width

I am not sure about what package version should I give it.
while this change is backward compatible, this also makes the circle radius comparatively smaller than the current version.
users might need to change the radius to a bigger number.

@Atishay-J Let's update the props type of Radius and the Stroke Width for this spinner to number? I think, we can not just support any number range for such value. If you have played around with configuration let's limit it with the type check. i.e: radius: 4 | 5 | 6 | 7 | 8 |. At least user will get a console warn if they tries to pass radius value outside of desired range. I think this is an issue with other spinner as well.

Please feel free to open a PR for other spinner if you like.

Rethink about the props type for the spinner. Number will make more sense and we can limit it to supported range.

[Atishay-J]

I agree, we can keep it a number.
But I think we should not have a limit to it, people may want to have granular control for the component.

In this case they can mix and match radius and strokeWidth according to their preference

I think it should be a major update, existing spinner would change its looks and feel silently.
