adding psr4 and replace to composer.json (#193)

when developing/testing, it's very useful to be able to install the entire contrib monorepo, eg to
enable installing a branch via a custom repository via composer.
Add missing psr4 namespaces and a replace section.
Add autoload->files so that autoinstrumentation etc continue to work.
