`PreCalculatedMSELoss()` raises `TypeError`

[eschibli]

Calling blurr.utils.PreCalculatedMSELoss() raises the following error:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

----> 1 PreCalculatedMSELoss()

     94 
     95 

TypeError: descriptor '__init__' requires a 'super' object but received a 'type'

This seems to be caused by a typo - super.__init__(...) should be super().__init__(...)

I'll take a look in next couple of days.
