Do not depend on default_backend when the backend is explicitly passed

[LostKobrakai]

Using Keyword.get_lazy and Keyword.put_new_lazy it is possible to not need to call for the default_backend and therefore not fail if it's not present (or needed).

Usecase is that I'd much rather have MyApp.CldrBackend.Money.to_string than needing configuration or passing opts. Basically like other cldr companion libraries work as well.

Great idea - I did not know about get_lazy or put_new_lazy and they are exactly what are required! Thanks for the suggestion, I'll get on it. I've been puzzling over this lately so great timing too.

I've updated ex_cldr and ex_cldr_numbers to use Keyword.get_lazy/3. I've updated ex_money as well in the one place where the non-lazy version was being used with a Cldr.default_backend/0.

You would also like me to add a Cldr provider module that generates a <backend>.Money module with an api like the other ex_cldr_* packages? Makes sense to me and it doesn't place a dependency on any of the other packages. I'll work on this today if I've understood you correctly.

Yeah, having it as another provides was what I was thinking about.

Added in ex_money version 4.3.0. Just add Money to the list of providers for a backend.
