Clarify delta calibration and geometry.
I had an issue with calibrating my delta printer, specifically on troubleshooting X-Y dimensions that were 88% of their target size. It was largely due to my misunderstanding of the delta geometry.
I was confused on what "delta_radius" means in klipper. It could mean bed radius or print area radius, but it is actually referring very exactly to delta kinematics-specific geometry. It is the X-Y distance between arm centers when in the parked position. The RepRap page on the topic is a useful place to learn a bit more about it.
This change provides an idea of a symptom of incorrect X, Y dimensional accuracy and provide a lead towards fixing it.
