[BUG] Shadows on Coil Blocks

[warjort]

Describe the bug I noticed when looking at #1583 that the shadows for coil blocks look wrong

For other blocks the bright part is front: top left top: front right

For coil blocks the bright part is kind of opposite but not quite front: bottom top: back

I haven't checked other faces.

Versions Forge: 14.23.5.2487 GTCE: 1.14.0

Expected behavior The shadows should look consistent.

I don't know what the correct fix should be. Change the textures? Apply some uv transformations in blockstates/wire_coil.json?

Screenshots Some casings and tile entities showing the issue

Comparison with apatite from forestry

There is no sort of "fancy render" stuff going on with these, it is just shading applied to the texture of the block itself. So I think just updating the texture would be the proper fix if we decide this needs to be addressed
