Utility function to use async functions as express handlers

```bash
yarn add @xpbytes/express-async-handler
```

```typescript
import { asyncHandler } from '@xpbytes/express-async-handler'

app.get(
  '/test',
  asyncHandler(async (req, res, next) => {
    const code = await Promise.resolve(204)
    res.sendStatus(code).end()
  })
)
```

You can optionally give a second argument `errorHandler`:

```typescript
function onError(err, req, res, next) {
  // ...
}

app.get(
  '/test',
  asyncHandler(async (req, res, next) => {
    const code = await Promise.resolve(204)
    res.sendStatus(code).end()
  }, onError)
)
```
