File upload for clojure spec

The current file upload wiki: https://github.com/metosin/compojure-api/wiki/Swagger-aware-File-uploads
only works with schema. How to do this with clojure spec? Thanks.

Start with the Swagger-aware File uploads wiki page linked in the issue and compare its schema-based guidance with the repository's Clojure spec support. Determine whether the project can document an existing file-upload path for clojure.spec or needs a defined implementation; done means the supported approach is clear in the documentation.
