[Suggestion]Variable Speed Inserters

A global upgrade to all inserters. When active in the tech tree, all inserters gain the ability to throttle their output according to what the player wants in a GUI. Minimum speed is 1 item per minute, maximum is the inserter's rated speed, and the desired rate in items/minute can be directly entered. For inserters with stack technology enabled, the GUI also grants an option to cap the number of items per stack, to a minimum of 2.

Thought up this when messing around on a modified playthrough, with vastly increased inserter speeds. While this made normal production significantly faster, it also makes blast drills near significantly harder to use correctly without significant waste on saves that dont use default inserter speeds.
