perform cyclic check for hue in test_rgb2hsv (#2477)

* perform cyclic check for hue in test_rgb2hsv

Test fails for cases when hue=0 and hue=360. As hue is cyclic in nature, add cyclic logic for checking the max difference by taking the sin of the tensor and then comparing the max values.

* address linter issues
