Recognize homogeneity between fractional aspect ratios #235

Different applications use different methods of writing aspect ratio. This causes a problem, for example, if you create a VF in Transkoder from a Clipster OV: Photon flags an error that essence files are not homogenous. Should Photon recognize that these two ratios are the same?

Clipster: <r1:ImageAspectRatio>256/135</r1:ImageAspectRatio>

Transkoder: <r1:ImageAspectRatio>4096/2160</r1:ImageAspectRatio>
