Issue Description:

A redstone conduit attached to a block that is adjacent to any liquid causes excessive render processing every time the liquid block considers flowing.

What happens:

As soon as you lay down this configuration of blocks, you can observe that the amount of time the F3 profiler shows being spent in root.gameRenderer.level.terrain_setup.rebuildNear.build near.unspecified approximately doubles.

The performance impact is easily observable in the profiler with just Ender IO installed. However, the impact is more significant in larger modpacks; in the motivating case (a custom modpack with 71 mods), this causes noticeable rendering jitter at a rate that appears to coincide with the rate that the liquid in question would flow at (ie, the spikes are further apart if lava is used than water).

The issue:

• Does not repro with other types of EnderIO conduits
• Does not repro with vanilla comparators, observers, or redstone trails
• Repros with a variety of different liquids and conduit-attached-blocks (but the rate of the performance spikes varies with the flow rate of the liquid)
• Repros regardless of whether the adjacent liquid is a source block or not
• Repros regardless of whether the conduit is set to input/output/both (but not if the conduit is adjacent-to-but-not-connected-to the block in question)

What you expected to happen:

This configuration shouldn't have noticeably worse performance than the same configuration without the liquid block.

Steps to reproduce:

1. Create a new empty world using the versions specified below
2. Dig a hole 1 block deep and fill it with water
3. Open the debug menu with Shift+F3 and navigate the pie profiler to root.gameRenderer.level
4. Attach a redstone conduit to any block adjacent to the water
5. Observe the increase in terrain_setup usage

Redstone Conduits are being Redone atm

Should be fixed in the current version; redstone conduits now again only send a redstone signal chwen it actually has changed.
