[FEATURE] I want to call an action from within another code step / action

Since actions are just functions that accept params and run saved JS code, I'd like the ability to call them within code steps. i.e. if I saved an action `printName`:

```javascript
async params => {
console.log(params.name)
}
```

I'd like to call that from another code step like so:

```javascript
const { printName } = require("@pipedream/actions")
if (name) {
printName(name)
}
```

(Ignore the proposed syntax, just a placeholder for functionality)
