Enable CI

This patch adds a CI config that builds and tests the library and runs
clippy and rustfmt.  To make the CI pass, it also fixes the formatting
and two clippy lints.  One of them is a breaking change:  We remove
AuthenticatorDataFlags::EMPTY.  Instead, AuthenticatorDataFlags::empty()
should be used.
