Transmit request to resize the canvas with Krita Output node (#52)

* Added Krita Resize node for plugin
* Registered canvas resize node to the __init__.py
* Removed resizenode and integrated it into the "Krita output"
* Quick update to simplify the node to return the re-sized image to krita instead of a json
