add FastLED YAML option for data rate (#1338)
* fix: FastLED SPI_DATA_RATE being truncated to 8 bits

FastLED expects SPI_DATA_RATE as an uint32_t, but we had it as uint8_t.
Fix that to avoid the data rate being truncated.

* fastled: allow specifying data rate

Previously, we've just taken the default data rate from FastLED.
However, that does not always work properly. In my case, I had a
slow level shifter that couldn't keep up with the 1 MHz data
rate default for WS2801. Long cabling might also be a reason why
one might want to reduce the data rate.

This will add a new optional "data_rate" config option where one
may specify the desired data rate as a frequency:

  light:
    - platform: fastled_spi
      chipset: WS2801
      data_pin: GPIO23
      clock_pin: GPIO22
      data_rate: 500kHz
      num_leds: 178
