Houdini Python Editor Node

Demo: https://vimeo.com/503806223

-----

Based on Maya Script Editor. This node is meant to be used for making simple/short Python script. It can also be used for pipeline related stuff: generating file, reading JSON, etc.

-----

This node DOES NOT replace the built-in Houdini Python Node.

Instead of executing the script automatically everytime the node is being used like the built-in Python node, the Python Editor node requires user to press the Execute button to run the Python script, just like the Maya Script Editor.

-----

Additional functions have also been added:

- Clear / Delete

- Save as .py

- Load .py
