Trying not to crash about tzdata

[h4cc]

Thanks, but that is not exactly what i meant.

I had something like this in mind:

# instead of this what will crash unnecessarily
{:ok, 200, headers, client_ref} = :hackney.get(url, [], "", [follow_redirect: true])

# refactor the code like this:
case :hackney.get(url, [], "", [follow_redirect: true]) do
  {:ok, 200, headers, client_ref} ->
    # rest of code
  error ->
    Logger.warn("Fetching #{inspect url} failed because of error #{inspect error}")
    error
end

That's probably because the url changed to https://data.iana.org/time-zones/releases/tzdata2017c.tar.gz- let me pr this quickly.
