This feature request came from #11

Instead of this:

async function processTask(task) {
   try { ... }
   catch (e) { reportError(e); ... }
}

We want to do this:

async function processTask(task, { reportError }) {
   try { ... }
   catch (e) { reportError(e); ... }
}

Does passing the function in this way change the default behavior outlined in #11 (comment) ?

@geoervin Great question! No it does not, it is just a simplification.

Instead of passing the reportError to both the queue and processTask function, users of the library just pass it to the queue and have it available in the processTask function if needed.
