Set minimum brightness for neopixel light

[purrplingcat]

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

I would like to limit minimum brightness for neopixel (like WS2812 and etc), especially if the gamma correction is higher than 3 to avoid led strip off if I set the low brightness. I need higher gamma correction for better colors of my WS2812 LED strip (like 4.2) but then I can't set brightness under 30% because the leds are going off even the light is on.

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

Add the min_power or min_brightness for neopixel light which will set the minimum brightness of light like the min_power for PWM output for lights using pwms (like RGB, RGBW, CWWW and etc). Also add max bvrightness will be good too,.
