This is an improved version of Filament Width sensor thing #636420, based on shadow casting idea by Flipper's #454584.
Now this sensor measures the filament width in three directions: -45, 0, and 45 deg. Three LEDs are sequentially light up and the sensor measures shadows from each direction. It (hopefully) compensate out-of-round filament shape.
45deg measurement limits the maximum measurable filament width around 2.5mm, so, unfortunately, this version is only applicable to 1.75mm filament. For 3mm filament, consider upgrade the line array sensor to wider one, such as TSL1402.
