Easing InOut

[SethHamilton]

It would appear that the easing options that go in reverse (inOut or back) result in an exception.

Easing option was removed in v0.4.0 and set to linear: https://github.com/kyo504/react-native-marquee/blob/49db5bfef3cf0880e9f29f34b8fdb99ba937f4b2/index.tsx#L61

Could easing option please be added again? Linear looks a bit cheap...

Easing InOut still missing in v0.5.0, @kyo504 any plans to bring it back or add a parameter to choose easing?

I am using the following package-patch for now:
