dataflash-re: reconstructing the Dataflash LWR lighting protocol

dataflash-re reconstructs the LWR control protocol used by Lightwave Research Dataflash xenon strobes. It combines 8051 fixture firmware disassembly, schematics and controller captures to document 9-bit serial frames, then implements an ESP32 bridge from Art-Net, sACN and TouchOSC to the original RS-485 link.
