 This is a DMX512 custom component for ESPHome that allows Arduino-based devices to control DMX devices via UART (this requires an RS485 module, see below).

 ## Implementation
 
 The implementation is based on other projects:

   * `periodic_update`: If set to false, only state changes are transmitted and the bus is silent in between - violates the specification and may cause some dimmers to turn off
   * `force_full_frames`: If set to true, the full 513-byte frame is always sent. Otherwise, only the configured channels are transmitted.
   * `custom_mab_len`: Set a custom mark-after-break length (in uS, default 12)
