Problem

While we are still reliant on barretenberg.wasm for blackbox functions, we can use the barretenberg.wasm file to compute these blackbox functions. It allows us to not need to compile barretenberg from source. It is pretty slow to compile in wasmer and slow in general.

Solution

We can reduce compile times by only including the necessary components in the .wasm file for blackbox functions. This reduces the compile times from 15seconds to zero on compilers like LLVM and cranelift (not sure why it takes so long) -- you can verify this using Wasmer.
