Release 1.2.0

Add contribute section to README

Add scm to project.clj for cljdoc

Move clojure dependency to dev profile

Prepare release 1.1.1

Extract tests into separate namespace

Using :test meta data on functions doesn't work well with modern clojure
tooling.

Avoid reflection by adding type hints

Head request must not return a message body

Delete unused stuff

Improve repo integration with cljdoc and sourcehut

Also drop codox configuration, the documentation is there for any IDE to
pickup and is also available on cljdoc.

Sourcehut build service recipe

Only runs tests.

Use LICENSE as filename for the software license

Release 1.1.0

Update codox

Drop org.clojure/data.codec dependency

As Louis-Philippe Véronneau noted this dependency is not required
anymore.  A Base64 encoder is provided by the JDK since Java 8, this
fact is also mentioned in the data.codec project.
