The translate function as a stable reference

[gorandalum]

We in AtB (the transport company in Trøndelag, Norway) actually use this library for the translations in our app.

Sometimes we translate something in a hook, and then we come into the situation where we need t in the dependency array to make the exhaustive-deps rule happy, but the t function is not a stable reference.

Would it be possible to use useCallback on the creation of the t function? By changing

return {
  t: (arg: any) => arg[language],
  language,
}

into

return {
  t: useCallback((arg: any) => arg[language], [language]),
  language,
}

I can create a PR if you think this is an ok change.
