Loads a PSF from fits and renormalizes it

        Parameters
        ----------
        pixel_scale
        file_path: String
            The path to the file containing the PSF
        hdu : int
            The HDU the PSF is stored in the .fits file.

        Returns
        -------
        psf: PSF
            A renormalized PSF instance
