A basic libpython-clj project

This will hopefully help reproduce an issue I have observed evaluating code with reveal enabled (reveal nREPL middleware) with nREPL 0.8.2, Clojure 1.10.2, and Java 14.0.1.

Steps

1. Connect through nREPL with the reveal middleware enabled.
2. Open src/io/scaleux/libpython_scratch.clj and start evaluating expressions therein. Please follow the instructions within the comment form to reproduce the issue.
3. Specifically, the form (py/att-type-map test-dict) results in an Exception with the following cause:

   1. Caused by java.lang.ClassCastException
      class java.lang.String cannot be cast to class clojure.lang.Keyword
      (java.lang.String is in module java.base of loader 'bootstrap';
      clojure.lang.Keyword is in unnamed module of loader 'app')

4. Running these forms in a new nREPL session without the reveal middleware evaluates the last expresssion fine and returns a map instead of raising an Exception.
