Improved calibration

I ran a calibration print of various size cylinders at different exposures and different intensities. The data can be found here. Note that none of the 0.5 mm or 0.3 mm cylinders printed.

It seems smaller details that are fully independent need more exposure and intensity than larger ones. The magic numbers for my projector are about 13 seconds for 3 mm diameter cylinders, and 15 seconds for 2 mm cylinders. Notably, none of the 3 mm cylinders are actually 3 mm, but 2.5 mm. The 1 mm cylinder was actually a little bigger, at 1.3 mm.
