    This is designed to run on stock Sensory Bridge hardware, and uses the Sweet Spot LEDs to receive data
    from the tool at https://sensorybridge.rocks/light_transfer/ when you hold your phone upside down 2-3
    inches above the LEDs! Binary data is sent through screen flashes and decoded by this Arduino Sketch,
    printing the result to the Serial Monitor. It uses a CRC8 byte at the end of every packet to determine
    the validity of the data sent, but no forward error correction like Hamming/Reed-Solomon codes yet.

    Unfortunately, I can't guarantee this works on anything but a stock Sensory Bridge with OEM LEDs, so
    this will never be the only option available for sending data to the device, but one of many.

// Draws an open-ended polygon using anti-aliased strokes with user-defined subpixel positioning, scaling and opacity.
// The coordinates of the vertices of your polygon are floating point values on or between LED coordinates, not 0.0-1.0
// like UV coordinates. Output is grayscale values (0.0-1.0) written to a global "float mask[Y_SIZE][X_SIZE]" array.
// Polygons are defined as a 2D array of vertices that form a vector shape, no closed shapes officially supported yet.
// On an ESP32-S3, this rasterizes the polygon very, VERY quickly.
