minimum/maximum brightness on light

**Describe the problem you have/What new integration you would like**

I would like to be able to set the minimum, and maximum brightness in a light component.

For the maximum brightness, I actually use color_correct: [50,50,50] in my config but a generic 'maximum brightness" option would be fine too.

Nothings exists yet for the minimum.

**Please describe your use case for this integration and alternatives you've tried:**

Actually, when I set the maximum brightness to 50% on all channels with the color_correct option in a light component, my leds doesn't light on when set to under 20% brightness when turn_on.

I would like to have a minimum 20% set in config so the light will be on when turned on
