feat(rating): add decimal support

[VishalGulati]

I am unable to give ratings in decimals using RatingModule. I want to have rating in decimals and the stars be colored as per the same. Currently if my rating value is 4.4 it is rounded off to 4 and if its greater than equal to 4.5 then it is rounded off to 5. Is this a known issue and undergoing change. Please share.
