generateProof workers won't exit

[pooryamoh]

Describe the bug
Wrote simple test code, for generating proof off-chain, after generating proof code won't exit and stop

To Reproduce
My Code:

const cljs = require("circomlibjs");
const { Identity } = require("@semaphore-protocol/identity");
const { Group } = require("@semaphore-protocol/group");
const {
  generateProof,
  verifyProof,
  calculateNullifierHash,
} = require("@semaphore-protocol/proof");

async function main() {
  const identity = new Identity("secret");
  const groupId = 1;
  const externalNullifier = 1212;
  const signal = 1;

  const group = new Group(groupId, 17);

  group.addMember(identity.commitment);

  const fullProof = await generateProof(
    identity,
    group,
    externalNullifier,
    signal,
    {
      zkeyFilePath: "./semaphore.zkey",
      wasmFilePath: "./semaphore.wasm",
    }
  );
  console.log(fullProof);
}
main();

Expected behavior
Logging fullProof and exit.

Hey @pooryamoh!

Here is more context about the issue you have: #318

A temporal solution could be to do something like this:

main().finally(() => process.exit());
