Write the function `pick` which creates a `hsl` color picker varying the `hue` and `luminosity` of the according to the position of the mouse, which:
- changes the `background` color of the `body`
- displays those 3 values, using the `text` class:
- the `hue` value in a `div` with the class `hue`
- the `luminosity` value in a `div` with the class `luminosity`
- the full `hsl` value
Write the function `pick` which turns the screen into a `hsl` color picker, varying the `hue` and `luminosity` of according to the position of the mouse, which:
- changes the `background` color of the `body`, so the `hsl` value is different on each mouse position on the screen:
- on the axis X, the hue value has to vary between 0 and 360
- on the axis Y, the luminosity value has to vary between 0 and 100
- displays those 3 values using the `text` class:
- the full `hsl` value in the middle of the screen
- the `hue` value in a `div` with the class `hue` in the top right corner of the screen
- the `luminosity` value in a `div` with the class `luminosity` in the bottom left corner of the screen
- copies that value in the clipboard on click
- displays two SVG lines, with respective ids `axisX` and `axisY`, following the cursor
> Here is how a hsl value is formatted: `hsl(45, 50%, 35%)`
