Some Compact Machine walls are invisible

[jchung01]

Bug Description

Compact Machine (CM) walls in a compact machine will be invisible if they are not in the lower subchunk (y<=47) of the machine. This bug is actually the same bug as Meldexun/Nothirium#63 as I assume Sodium/Vintagium also splits the blockstate data between subchunks. Yes, it is CM's fault that they aren't taking y value into account when rendering the sides, but the bug is only exhibited with such performance mods (see last comment in the Nothirium issue for more info).

I provided a fix through mixin into CM in Meldexun/Nothirium#88, so you can do what you like with that code. Please let me know if the fix would be more appropriate to include into UniversalTweaks as this is a mixin into a mod for compatibility, and I can open a PR there. I can confirm the fix works even for this mod.

Reproduction Steps

Using:

• Compact Machines: 3.0.18-b278
• Vintagium: build from commit b60cf92

1. Place a Normal, Large, Giant, or Maximum Compact Machine.
2. Enter the compact machine by right clicking it with a Personal Shrinking Device.
3. See that the Solid Compact Machine Walls at y=48 and above are invisible.

It's better to PR the fix to the UniversalTweaks since it happens not only with Vintagium
