FastLED support

[materight]

I'm trying to build an ESPHome image for a bk7231n device that controls an addressable LED strip. So I've added this component:

light:
  - platform: fastled_clockless
    chipset: WS2811
    pin: P17
    num_leds: 43
    rgb_order: RGB
    name: light

when I try to build it, I first get:

Internal Error: require_framework_version does not support this platform configuration
    platform: bk72xx
    framework: arduino

I assumed it was just a missing check, so I added a condition for CORE.is_libretiny here and recompiled, but I get this:

Is FastLED not supported yet or am I missing something?
