Separate processor with ES module syntax not working

Created by: ddavid67

Description

Currently you can't use a processor coded with ES module syntax (export keyword) It works by importing the job into index.mjs, but I want to separate processes.

Test code to reproduce

index.mjs

let queue = new Queue('queue');
queue.process('/processor.mjs');

processor.mjs

export default async (job) => {
return 'job completed;
}

result

internal/modules/cjs/loader.js:712
    throw new ERR_REQUIRE_ESM(filename);
    ^

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /processor.mjs

Bull version

v3.4.1
