C# Wrapper

[Renari]

Is your feature request related to a problem? Please describe.
Currently to call phantom camera methods in C# you have to do something like this:

var action = GetNode("BeehaveTree").Call("get_running_action");

Currently to use beehave in a C# project requires calling GetNode("node").Call("xxx") with strings functions names. This is prone to causing runtime issues, for example if beehave changed a method this would still compile in C#.

Describe the solution you'd like
Beehave could ship a C# wrapper that would prevent the above from happening.

Additional context
One such example:
https://github.com/Portponky/better-terrain/blob/main/addons/better-terrain/BetterTerrain.cs

var action = GetNode<BeehaveTree>("BeehaveTree").getRunningAction();

This also heavily eases use within IDE, because through this wrapper we can use known type declarations instead of everything coming through as GodotObjects.
