TSL2585(3) is a light sensor that can also handle IR and UVA

The TSL2585 is a light sensor that can also handle IR and UVA. We're pretty close to wrapping up all the prototypes for ams-OSRAM light sensors of interest... this one is a light sensor that also has UVA reading, so it's handy for outdoor sensing where you may want to know how much UV light is being emitted for skin health.

@adafruit I wonder if I could use it to estimate cyanotype exposure times. I shall have to investigate.
