holdToDisplay should be 1s by default only for touch events.

I find the holdToDisplay feature useful only for touch, in desktop it's not very useful.

I would change the default option to be 1s for touch and 0 for mouse events.
The holdToDisplay option will have the following interface:

```
type HoldToDisplayConfig = {
({ touch: number } | { mouse: number })
}

interface ContextTriggerConfig{
holdToDisplay: number | HoldToDisplayConfig,
...otherOptions
}
```

With the default value being:

```
const defaultHoldToDisplay = {
mouse: 0,
touch: 1000
}
```

If a number is given it will apply to both touch and mouse.
Also, this will require a major version bump as it will be a breaking change.

I'll implement this myself during the next days, meanwhile if somebody shows up and wants to take care of this, I'll be more than happy.
