/**
 * Converts an RGB colour to HSV.
 * Conversion formula is based on the RGB to HSV conversion algorithm:
 * https://en.wikipedia.org/wiki/HSL_and_HSV#From_RGB
 *
 * https://www.niwa.nu/2013/05/math-behind-colorspace-conversions-rgb-hsl/
 * - Hue (h) is calculated based on the maximum RGB value.
 * - Saturation (s) is the chroma divided by the maximum RGB value.
 * - Value (v) is the maximum RGB value.
 * @param r Red channel (0-255)
 * @param g Green channel (0-255)
 * @param b Blue channel (0-255)
 * @returns HSVColour object with h (hue), s (saturation), v (value)
