Updates for ex_cldr 2.38.0 + bug fix

[kipcole9]

When using ex_cldr_territories version 2.8.1 from hex, compilation fails with ex_cldr version 2.38.0 released yesterday. However ex_cldr_territories from master works perfectly fine so hopefully you're able to publish an update soon?

In running the tests with ex_cldr version 2.38.0 there are some data changes which made some tests fail due to either a difference in data sort order or because 2 doctests expected Cuba to have two currencies (the CUP has now been discontinued - so I changed the tests to use Haiti which still has two currencies).

Summary of changes

• Return {:error, reason} when Territory.info/1 has no info
• Make currency info sorted to be deterministic
• Fix info tests (CUP no longer exists, use :HT example since it has more than one currency)

@kipcole9 Can you rebase this and only keep the changes to Cldr.Territory.info, since I believe that the other bugs have been addressed in #43
