Feature Request: Provide more animation options

[MickL]

Really love this package but I encountered a few limitations when using it. Providing more options to some animations would be amazing:

• bounce should have a direction property to control in which direction it bounces, usecase: an arrow could bounce to the right or left but bounce can currently only bounce to the bottom
• bounce should have a distance property to control how much it bounces, usecase: something big will only bounce slightly with the current setting
• tada should have a scale property to control how much it scales, usecase: the current default might be to slightly to pop out of the other content (in contrast heartbeat has a scale property)
