README about programatically toggle the menu isn't correct

[d10sfan]

Using the latest in the master branch, the toggle code examples don't work (https://github.com/godot-extended-libraries/godot-debug-menu#usage).

If I do that, I get errors that the Canvas does not have those properties.

If I instead do this:

var debug_menu = DebugMenu.get_node("DebugMenu")
debug_menu.style = debug_menu.Style.VISIBLE_COMPACT

Then as well the NONE should be HIDDEN instead

var debug_menu = DebugMenu.get_node("DebugMenu")
debug_menu.style = debug_menu.Style.HIDDEN

I'm not sure if this is expected behavior or not, if it is I could open a PR for some README changes.

This was likely changed by 2d1bf27, and is an unintended consequence.

The correct fix is to put the script on the CanvasLayer instead of a child Control node, so that you can set properties directly on DebugMenu instead of having to use get_node(). Feel free to open a pull request for this 🙂

Ah gotcha, I'll see if I can make that work locally and if so provide a PR soon.
