reactStringReplace should take/return ReactNodeArray

fixes #43

I commented my thoughts at the specific lines.

I would be happy to discuss this with you @iansinnott :)

Also any feedback from others seeing this PR is very welcome, since I would not consider myself a typescript expert.

Are React.ReactNodeArray and React.ReactNode built in to typescript? Where are they defined?

[monsterkrampe]

These are defined in the react type definitions just like JSX.Element which we had before.

I would suggest adding react as a peerDependency anyway, but this depends on how you intend to use react-string-replace. Just seeing the code, one could assume that this module can be used for anything, not just react.
If this is your intention, I would not like to use React.ReactNode and so on and I would also not add react as a peerDependency.
But since I think that it is indeed intended to use this module only in combination with react, I think react should be added as a peerDependency, although I'm not sure which version.
(hope this is not too off topic)

Let me know what you think.

Yeah exactly, even though the code isn't React-specific in practice I would think everyone's using it with React. So I'm happy with the React-centric type definitions.

Thanks for the clarification about where the definitions come from.
