WIP: Max volumetric speed calibration

Qidi own profiles are eagerly fast. For example their profile for Qidi own gray Rapido PLA max volumetric flow is set to 25mm³/s, while realistic quality print speed is more around 18-22mm³/s. Some lucky people have reported that they can also go up to 35-36mm³/s with stock config

Since out of box there's no way knowing at what flow you can archive need to make test for it. Easiest way to test it is using OrcaSlicer built-in calibration
