Adds 3 new logistics items that balance the input AND output lanes of a belt perfectly (one for each speed of transport belt). Items from both input sides of the belt are placed on both sides of the output belt in an alternating fashion. If only one lane is available for output either due to a T-Junction or the other lane being backed up, then items from both input lanes will be placed on that single output lane. Can be connected to belts, splitters, and underground belts. Behaves for the sides/lanes of a single belt similarly to how a normal splitter behaves with 2 belts connected in and out.

Each balancer type (yellow, red, & blue) unlocks using the same logistics 1-3 research as the corresponding splitter type. Requires the same ingredients as that tier's splitter to build, but at roughly 1/2 the amount for each ingredient.

Based on the Single-Splitter mod (huge thanks to Razorin & Aidan647), but adds support for all 3 belt speeds and the ability to connect to splitters and undergrounds.
