HueComponent direction vertical does not account for slider

[newmanw]

When using HueComponent with direction vertical, the default slider/pointer css is not adjusted.

Work around is to pass in a custom 'pointer'. If vertical is an out of the box option should a default slider for the vertical hue also be included.

seems to be working for me

<color-hue-picker
  [color]="state"
  (onChangeComplete)="changeComplete($event)"
  (onChange)="changeComplete($event)"
  [direction]="'vertical'"
  [width]="18"
  [height]="300"
></color-hue-picker>
