Rewrite CI based on Mint

Tests are run in a matrix against a few Elixir and OTP versions.

Mint.WebSocket should be able to support Elixir as low as 1.5.5 like
Mint has in its CI. The test dependencies on Cowboy and Ranch need OTP
21+ for the new stacktrace syntax so we only test as far back as 1.6.6.
