Added a function that will pad an image to an even dimension in width and height

src/MATLAB/+MovieUtils/PadEven.m

+function imOut = PadEven(im)
+    cPad = mod(size(im,2),2);
+    rPad = mod(size(im,1),2);
+    
+    imOut = zeros(size(im,1)+rPad,size(im,2)+cPad,size(im,3),'like',im);
+    imOut(1:size(im,1),1:size(im,2),:) = im;
