Clojurians Log v2

coercion works for all :parameters, even :headers

we might not have an example of this, but it works in exactly the same way as :query parameter coercion

Please check the tests: https://github.com/metosin/reitit/blob/master/test/cljc/reitit/ring_coercion_test.cljc

You probably want to validate it in a middleware.
