Support for IS31FL3216 LED driver

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

I would like the IS31FL3216 LED driver to be supported as a light component. This driver can be found on the LYRATD-MSC from espressif: https://docs.espressif.com/projects/esp-adf/en/latest/design-guide/dev-boards/get-started-esp32-lyratd-msc.html

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

This board can be a good alternative to the Google Home mini, the external DAC is already working fine with ESPHome (albeit without trigger words support), the LEDs would be nice to indicate when it is listening, processing commands, etc...

**Additional context**

Here's the driver code from the Espressif Audio Development Framework: https://github.com/espressif/esp-adf/blob/master/components/esp_peripherals/lib/IS31FL3216/IS31FL3216.c
