The TSL2591 is special because it can read to low light level (188microlux). there are a few problems with the Universal sensor definition:
sensor -> resolution = 0.0001 (currently = 1.0)
Also the calculateLux function is set to a uint32_t when it should be a float (currently it tuncates the result to an integer).
even with these changes though event.light still truncates the value to 2 decimal places. I can't seem to figure out why.
