lightmanager for raylib

use edited rlight.h from shader raylib example


use shader lighting from shader raylib example

## Example 

```cpp

#include "raylib.h"

#include "lightmanager.h"

int main(void)

{

    // Initialization

    //--------------------------------------------------------------------------------------

   // float fraq = GetMonitorWidth(0)/GetMonitorHeight(0);

    const int screenWidth = 1000; //GetMonitorWidth(0);

    const int screenHeight = 600;//GetMonitorHeight(0);

    InitWindow(screenWidth, screenHeight, "raylib [core] example - basic window");

    SetTargetFPS(60);   // Set our game to run at 60 frames-per-second

    Camera camera = { 0 };

    camera.position = (Vector3){ 40.0f, 40.0f, 0.0f }; // Camera position

    camera.target = (Vector3){ 0.0f, 0.0f, 0.0f };      // Camera looking at point

    camera.up = (Vector3){ 0.0f, 1.0f, 0.0f };          // Camera up vector (rotation towards target)

    camera.fovy = 45.0f;                                // Camera field-of-view Y

    Vector3 position = { 0.0f, 0.0f, 0.0f };

    camera.projection=CAMERA_PERSPECTIVE;

    Model mod = LoadModel("asset/ship_Awing_gene.glb");

    float rot = 0;

   

    LM_Init();// light manager init

    LM_AddPointLight((Vector3){15,15,15},(Vector3){0,0,0},WHITE); // add light point

    LM_AddPointLight((Vector3){-15,15,15},(Vector3){0,0,0},GREEN);

    LM_AppliShader(&mod);// appli shader to model

    while (!WindowShouldClose())    // Detect window close button or ESC key

    {

        BeginDrawing();

        ClearBackground(BLACK);

        BeginMode3D(camera);

        DrawModelEx(mod,(Vector3){0,0,0},(Vector3){0,1,0},rot,(Vector3){1,1,1},WHITE);

        rot = rot +5*GetFrameTime();

        EndMode3D();

        EndDrawing();

    }

    UnloadModel(mod);

    LM_Unload();// unload light shader

    CloseWindow();        // Close window and OpenGL

    return 0;

}
