Repo for implementations of various Transformer Attn mechanisms [P]

Initially, I developed this so I can easily switch between different Attention mechanisms for my Small Language Model (SLM) experiments and benchmarking. However, I also realized that these implementations can be applicable in Computer Vision, modernize Vision Encoders, RL, and others. I hope this helps researchers, students, or educators in general. I also included MiniMax M3's sparse attention. This can be integrated with Andrej Karpathy's autoresearch framework. For contributing: I encourage you to please open a PR.
