Publish Updated Version of Package

[nelsonic]

In light of the updates made in #63 we should publish a new version of this package so that people using the latest Ecto/Phoenix do not get warnings ...

I'm opening this issue instead of just doing it, because I'm on a questionable Wifi connection and Hex.pm is rejecting my auth request:

mix hex.user auth
Username: nelsonic
Account password:
Generating keys...
Generation of key failed
{:failed_connect, [{:to_address, {'hex.pm', 443}}, {:inet, [:inet], {:option, :server_only, :honor_cipher_order}}]}

So I'm guessing there is a MITM intercepting requests here ...
i.e. don't use public Wifi for anything important!

according to: elixir-lang/elixir#9374 (comment)
had to run:

mix local.hex --force

Now both mix deps.get and mix hex.user auth work! 🎉

New version is 2.2.0 because it includes new callback functions and an updated in-band dependency but no breaks in backward compatibility.

Thanks again @veverkap for the great contribution. 🥇
