Enhance model card for TLB-VFI: add metadata, links, and usage

This PR significantly enhances the model card for the `ucfzl/TLBVFI` model by:
- Adding `pipeline_tag: image-to-video`, ensuring the model is discoverable under relevant tasks on the Hugging Face Hub.
- Specifying `library_name: diffusers`, which is the appropriate library for this diffusion model, enabling future integration and clearer usage guidance.
- Including `license: mit` for clarity on usage terms.
- Incorporating the full paper abstract to provide a comprehensive overview of the model.
- Adding direct links to the official project page and the GitHub repository for further details and code access.
- Embedding key images from the GitHub repository to visually explain the model and its results.
- Providing practical command-line usage examples for immediate inference, based on the GitHub repository's instructions.
- Including the BibTeX citation for proper academic attribution.

These changes will greatly improve the discoverability, usability, and documentation of the model on the Hugging Face Hub.

+## Abstract
+
+Video Frame Interpolation (VFI) aims to predict the intermediate frame $I_n$ (we use n to denote time in videos to avoid notation overload with the timestep $t$ in diffusion models) based on two consecutive neighboring frames $I_0$ and $I_1$. Recent approaches apply diffusion models (both image-based and video-based) in this task and achieve strong performance. However, image-based diffusion models are unable to extract temporal information and are relatively inefficient compared to non-diffusion methods. Video-based diffusion models can extract temporal information, but they are too large in terms of training scale, model size, and inference time. To mitigate the above issues, we propose Temporal-Aware Latent Brownian Bridge Diffusion for Video Frame Interpolation (TLB-VFI), an efficient video-based diffusion model. By extracting rich temporal information from video inputs through our proposed 3D-wavelet gating and temporal-aware autoencoder, our method achieves 20% improvement in FID on the most challenging datasets over recent SOTA of image-based diffusion models. Meanwhile, due to the existence of rich temporal information, our method achieves strong performance while having 3times fewer parameters. Such a parameter reduction results in 2.3x speed up. By incorporating optical flow guidance, our method requires 9000x less training data and achieves over 20x fewer parameters than video-based diffusion models.

+## Overview
+
+TLB-VFI leverages temporal information extraction in the pixel space (3D wavelet) and latent space (3D convolution and attention) to improve the temporal consistency of the model.

+
+### Inference Example
+
+You can perform inference using the provided scripts on the GitHub repository. Please ensure you have downloaded the trained model weights.
+
+To interpolate 7 frames in between `frame0` and `frame1`:
+
+```bash
+python interpolate.py --resume_model path_to_model_weights --frame0 path_to_the_previous_frame --frame1 path_to_the_next_frame
+```
+
+To interpolate 1 frame in between:
+
+```bash
+python interpolate_one.py --resume_model path_to_model_weights --frame0 path_to_the_previous_frame --frame1 path_to_the_next_frame
+```
