Implement Initial L-System for Procedural Vegetation Generation

[M1thieu]

Initial implementation of the L-System algorithm for procedural vegetation generation in LP. The key features and changes included in this commit are:

• LSystem.gd: Defines the core L-System logic, including the generation of L-System strings based on given parameters such as axiom, rules, angle, length, and iterations. It also includes methods for setting and getting these parameters.
• LSystemManager.gd: Manages the initialization and interaction with the LSystem class.
• LSystemRenderer.gd: Responsible for rendering the generated L-System string. It connects to the LSystemManager to get updates, and includes a temporary wind effect based on the cursor position for testing purposes.
• Wind Integration: A temporary wind effect is applied to the L-System rendering based on the cursor position to simulate wind forces on the plant structure.
• Also organized the project a little more (PascalCase for files) and reduced output of the save game function

Closes #71

As an addition you can also look at the temporary wind effect applied for now, enhancements would be needed later but the main idea is here

Thanks for gif, this will absolutely help to define the foundations of the vegetation and even later other fractals (such as snowflakes) !
