build(deps): Bump req from 0.3.11 to 0.4.2

[dependabot]

Bumps req from 0.3.11 to 0.4.2.

Release notes

Sourced from req's releases.

v0.4.0

Req v0.4.0 changes headers to be maps, adds request & response streaming, and improves steps.

Change Headers to be Maps

Previously headers were lists of name/value tuples, e.g.:

[{"content-type", "text/html"}]

This is a standard across the ecosystem (with minor difference that some Erlang libraries use charlists instead of binaries.)

There are some problems with this particular choice though:

• We cannot use headers[name]
• We cannot use pattern matching

In short, this representation isn't very ergonomic to use.

Now headers are maps of string names and lists of values, e.g.:

%{"content-type" => ["text/html"]}

This allows headers[name] usage:

response.headers["content-type"]
#=> ["text/html"]

and pattern matching:

case Req.request!(req) do
  %{headers: %{"content-type" => ["application/json" <> _]}} ->
    # handle JSON response
end

This is a major breaking change. If you cannot easily update your app or your dependencies, do:

# config/config.exs
config :req, legacy_headers_as_lists: true

This legacy fallback will be removed on Req 1.0.
