The internal_yuv_hybrid_compare function was doing the image size check which doubles the checks over internal_yuv_hybrid_compare's. move this to yuv_hybrid_compare and check all 3 channels to avoid double checking when using rgb images and check all channels with yuv_hybrid_compare

avoids using mixed syntax for lifetimes, per clippy's #[warn(mismatched_lifetime_syntaxes)]

| Then check split success | |
| Then the split channels match the references |
then steps should be formulated in passive, but this is just a hint - I can fix this later :)

i will keep that in mind for future use- was the first time i'd worked with that test runner

To solve #12 in a fairly user friendly way, exposes the
Decomposetrait, rgb/yuv conversion, and ayuv_hybrid_comparemethod. As well as fixing some visibility issues that arose from exposing theutilsmodule.These changes are hidden behind the "yuv_compare" feature flag since it will, in general, probably not be needed by the majority of users. But in more performance critical areas it can yield a good speed boost such as in my more recent project which benefited greatly from swapping to yuv to avoid a significant amount of data copying and format conversion. In other cases where one can use yuv rather than rgb, a similar potential exists. The speed boost is not as great as one may see with gpu-based comparison however it is enough to justify the possibility, saving 5-10% of runtime for me in some cases.
