Validation of format on [s]printf

[trejjam]

Hi, first thank for a great idea with the /safe package.
I found out that using functions [s]printf from Safe namespace make PHPStan\Rules\Functions\PrintfParametersRule not working (it does not validate a number of parameters anymore)

Indeed, since the function used is Safe\sprintf instead of sprintf alone, the rule is not triggered anymore.

I would need to reimplement the rule for Safe\sprintf in the Safe PHPStan extension.
I don't know if this is easy to do yet. I'll keep the issue open until I have some time to figure that out.
