Write a function named hexToRGBColor that takes a hexidecimal color code string in the format of "#RRGGBB"
and returns the rgb code string in the format of "rgb(r, g, b)" where "r", "g", "b" are the decimal values corresponding to the hexidecimal values "RR", "GG", "BB" respectively. Recall that the range of a two-digit hexidecimal code is "00" to "FF" which corresponds to the decimal range 0 to 255, inclusive ("F" has a decimal value of 16).
For example, the call hexToRGBColor("#000000") should return the string "rgb(0, 0, 0)" and the call hexToRGBColor("#c0ffEE") should return the string "rgb(192, 255, 238)".
You may assume the passed string starts with a "#" character followed by 6 hexadecimal characters. Your function should ignore
casing for the 6 non-numeric hexadecimal values (letters A thorugh F).
