removes IEDs, these are its replacement

this recipe produces a finished pipebomb

you can craft pipes (of the atmos kind) with some metal
then you can make it into a pair of halved pipes with a welder
then you stuff in items for extra effect (optional, only works if it
does something)
then you put in welding fuel OR gunpowder (no other options as of now,
gunpowder is a better explosive)
cable finishes that part
after that, you can attach an unsecured assembly to finish the bomb

also this is the math for the explosion, power is decided by fuel

using it in-hand activates the assembly, using it off-hand allows you to
configure the assembly

## Why It's Good For The Game

IEDs suck and stuff and this would be a better upgrade/replacement
because with assemblies you could make a circuit sentient pipebomb or
gift a pipebomb via cargo or something and gimmicks i guess
