Trigger for clientside callbacks

[frnhr]

From TriggerTransform:

NOTE: This transform cannot be implemented for clientside callbacks since the JS can't be modified from here.

I respectfully beg to differ.

We can wrap the callback JS function in another function which takes out the trigger args.

Roughly like this:

// original callback:
function(important, _irrelevant, interesting) {
    return important * interesting;
}


// wrapped callback:
function(important, _irrelevant, interesting) {
    const func = function(important, interesting) {  // <-- '_irrelevent' removed
        return important * interesting;
    };
    return func(important, interesting);
}

Implementation is in this PR.

Ah, yes, you are correct! Very elegant solution - I didn't think of that at the time ;)
