转换问题
感谢制作这个工具！
不过我刚做了一些RGB2HSL, HSB的转换。为了验证准确性，转换回去看了一下。发现RGB2HSL中L的值一直是有一些问题，H和S正确，RGB2HSB正确。转换回去的功能上HSB2RGB整体有一些问题。因为没有读代码，主要是发出来也希望后续的使用者会注意到这个问题。
rgb2hsl方法，有一处写错了
第98行，计算s的第三个if，应该改成(max - min) / (2 - (max + min))，参考wiki
//计算s
if ( l == 0 || max == min ) {
s = 0;
}else if ( 0 < l && l <= 0.5 ) {
s = ( max - min ) / ( max + min );
}else if ( l > 0.5 ) {
s = ( max - min ) / ( 2 - ( max - min ) ); // 这里有误
};
