Insertion Deletion Denoising Diffusion Probabilistic Models (wip)

Implementation of Insertion Deletion Denoising Diffusion Probabilistic Models. This scheme basically allows for DDPM to work beyond just in-place corruption along the sequence. They try to apply this to text generation with lukewarm results. I think it holds promise for protein design, as it would be able to infill certain regions without being constrained to a fixed number of amino acids.
