Feat decide toggle

[andresz1]

Description

This PR:

• Enables useDecision to prevent sending impression tracking events to both Optimizely and Segment by setting isEventDisabled to true
• Introduces a new hook, useDecisionCallback, which allows for programmatic calls to decide, making it useful for user event callbacks.

Example

const {decide} = useDecisionCallback()

const handleClick = () => {
  const data = decide('x')
}

const {decide} = useDecision('x', { isEventDisabled: true }) 
// impression won't be tracked

This allows the decide function to be called programmatically, which is useful for very specific use cases. 99% of cases useDecision will be just fine
