Option to Hide Toast on Navigate

[Keenan-Softserve]

Is your feature request related to a problem? Please describe.
I want to be able to decide when a toast should persist when navigating to a new screen (using react-navigation).

Describe the solution you'd like
When displaying a toast Toast.show() one of the ToastShowParams (ToastOptions) should have a 'persist:boolean' that determines if the Toast should persist when the screen changes or not.

Additional context

• I'm mainly using this package for displaying errors. Sometimes I redirect the user to a different screen than the one that produced the error and want to use a Toast to display the error on the new screen (so it should persist, the way it already does).
• Other times I don't want to force the user to swipe the Toast away, but I also don't want to set a timeout. It should go away once the screen changes.
