Bundled Cable compatibility with ComputerCraft is broken about projectred

Thanks for looking into this. Definitely seems like remnants from when we moved from Scala to Java.

According to the old Scala code, ITransmissionAPI#getBundledInput should give you the incoming signal to the block specified, meaning it will offset the given pos towards the face, then ask that neighbor block for its output. The function BundledSignalsLib.getBundledInput actually does this (see line 36), while the other does not (I believe I started writing this method in TransmissionAPI, then realized it fits better in BundledSignalsLib, copied it there, and forgot to redirect the call).

This is also why the IBundledRedstoneProvider I implemented offsets the side/face. Your API is an output getter, while mine is an input getter, so it has to operate from the other block's perspective. At the time, both of our APIs were stable so I couldn't just change mine to match unfortunately. Maybe I'll revisit it.

So overall, I think we fix it like this:

1. For ProjectRed -> CC, point TransmissionAPI.getBundledInput to BundledSignalsLib.getBundledInput. This alone should fix probing.
2. For CC -> ProjectRed, like you said, there's a bug with the sides that PR's cables are querying interactions with. Looking into this now.

Found it! Here, the Bundled Cable asks its neighbor for a bundled signal. This line specifically is for registered interactions. For whatever reason, it's using the rotation index rather than converting it into a direction index.

ProjectRed/transmission/src/main/java/mrtjp/projectred/transmission/part/BundledCablePart.java

Line 234 in 292850d

byte[] externalSignal = BundledSignalsLib.getBundledSignalViaInteraction(lookup.tile.getLevel(), lookup.tile.getBlockPos(), Direction.values()[lookup.r]);

Instead it should be doing what line 230 does, converting that rotation to direction.

Same deal with Bundled gate parts:

ProjectRed/integration/src/main/java/mrtjp/projectred/integration/part/BundledGatePart.java

Line 89 in 292850d

return BundledSignalsLib.getBundledSignalViaInteraction(lookup.tile.getLevel(), lookup.tile.getBlockPos(), Direction.values()[lookup.r]);
