Bug:
===

* The plugin does not support calls to 'curl http://localhost:8042/tools/reset -d ""' 
  if the script registers the OnChangeCallback. 
  https://discourse.orthanc-server.org/t/problem-when-restarting-orthanc-via-api-tools-reset/5183
  Ex:

    import orthanc

    def OnChange(changeType, level, resource):
      print("OnChange")
    orthanc.RegisterOnChangeCallback(OnChange)


Possible improvements:
=====================

* In ReceivedInstanceFilter: change the orthanc.InstanceOrigin enum for an 
  object similar to the origin table in lua for the Python Plugin?

* Allow working with python virtual env (since python 3.11, we must sometimes use --break-system-packages).

* Allow registering multiple callbacks when you want to install multiple independent python plugin (ex: RegisterOnChangeCallback).
  Right now, there is a singleton in python for each callback.

Primitives the Orthanc community is missing
===========================================

* Create Python jobs:
