fix: Fix for more recent casbin versions and connection send fix (#12)

* Update requirements.txt

Allow the watcher to be used with casbin versions more recent than 0.8.4.

* Fixed subscriber send function

Replaced call to process_con.put() with process_conn.send().  Trying to call .put() throws the error: AttributeError: 'Connection' object has no attribute 'put'
 (at least on MacOS)
