Cauldron should be fluid_storage peripheral

[tonitch]

Useful information to include:

• Explanation of how the feature/change should work.
• Some rationale/use case for a feature. My general approach to designing new features is to ask yourself "what issue are we trying to solve" and then "is this the best way to solve this issue?".

I might be wrong, but it seems like cauldron are not using fluid_storage. This would be handy.

Since there is possibility to produce lava in a cauldron, an excellent use case for this interface would be to make an automated lava farm that would power up turtles and the network would use networking cable.

I haven't tested that, but I suppose almost everything is already set. We just have to let the cauldron be fluid_peripheral.

The reason that cauldron is not fluid_storage is because forge did not make it implement the FluidHandler capability

Do you think it could be fixed on cc:t 's side or maybe this should be an issue for forge?

No, no. This is 100% a bug on CC:T's side.

So for some history/context here, inventories and fluid tanks used to only be available on block entities. However, some blocks (like caldrons and composters) don't have a block entity associated with them, but still can behave as an inventory/tank.

Older versions of Forge (anything before MC 1.20.4) didn't really handle this correctly (though Fabric does!), which is why cauldrons aren't available as peripherals. However, NeoForge does support this — the issue is that CC:T has not updated it's generic peripheral code to handle that. There are some wider issues that affect generic peripherals on recent versions of the game (see also #1817), so that whole system probably needs a rewrite.

As far as MC 1.20.1, this is unlikely to be fixed, at least not without special handling for cauldrons.
