Misaki 9a1069db90 Add HDR files and improve light handling ...

Added three binary files: `golden_gate_hills_1k.hdr`, `rogland_sunset_1k.hdr`, and `studio_small_03_1k.hdr`.
Added a new inline function `weight_nee_light` in `BSDF.h` to compute the weighted contribution of light based on the next event estimation (NEE).
Added a new function pointer type `sky_free_f` in `Light.h` for freeing sky light data.
Added a new structure `hdr_sky_data_t` in `SkyLight.h` to hold HDR sky data, including texture and intensity.
Changed the `RAY_EPSILON` definition in `Common.h` to a new value.
Changed the `light_collection_free` function in `Light.h` to include freeing sky light data if it exists.
Changed the `sky_create_hdr_sky` function in `SkyLight.h` to initialize HDR sky data and compute marginal and conditional distributions.
Changed the `texture_load` function in `Texture.h` to accept a `stride` parameter for different texture formats.
Changed the `evaluate_bsdf_directional` function in `LightEvaluation.c` to handle light intensity checks.
Changed the `evaluate_bsdf_const_sky` function in `SkyLight.c` to use a pointer for sky data and added checks for intensity.
Removed TODO comments related to handling triangle and material removal in `Triangle.h` and `Light.h`.
Removed the old `weight_sky_light` function in `SkyLight.h` and replaced it with the new `weight_nee_light` function.
Updated the `scene_setup` function in `main.c` to change camera position and light direction, and to load HDR textures.
Increased the sample count in the rendering configuration in `main.c` for better quality rendering.
