bug whith slycing to get the bay_img in lfp_decoder

[gor-g]

On raw images taken with a modified Nikon camera, in comp_bayer(), the line a0 = (t0 << 4) + ((t1 & 0xF0) >> 4) gives

(ValueError('operands could not be broadcast together with shapes (13408599,) (13408598,) '),)

i don't really get what bay_img is but if it's the bayer image, you could do self._bay_img = rawpy.imread(self._lfp_path).raw_image.astype('float') innstead of calling self.comp_bayer(). (It uses the rawpy library)
