Clojure(Script) support for muuntaja

[ikitommi]

Negotiating formats should be symmetric, on both server & client. Also for ClojureSript. Should run on Node too.

Hey @ikitommi, curious if this is still relevant and open for PRs, and if this port would make the muuntaja middleware usable from node as well e.g. in macchiato/reitit.

happy to help if possible! where would you point someone looking to get started?

PR for this would be most welcome!

I think most of the code should map nicely from clj to cljc. The major differences are that muuntaja.format.json should use js/JSON instead of Jsonista, exception handling might have different types and return types (steams, bytes) might need to work differently.

For the JSON format, the macchiato code might help.

When all the tests work both on the CLJ & CLJS, I think it's mostly done.

There is a working cljs tests setup in https://github.com/metosin/reitit, to run locally & in the CircleCI.
