Update pyproject.toml

- Changed FlipStreamChatJson: `temperature` and `top_p` are now inputs.
- Add FlipStreamViewerVideo: streams frames and optional audio to the viewer.
- Add FlipStreamFileSelect_DiffusionModels.
- Add FlipStreamLogger.
- Some fixes.

-
-- Use more higher-quality checkpoint models.
-- To enhance stability between frames, use a deliberate prompt in the 'pre text' to establish a consistent background, such as `ideal background, on desk`.

-## To Avoid OOM
-
-- The ComfyUI commandline option '--reserve-vram 2' may good, it will work as buffer.
-- Edit comfy code using try except pass around error points may practical for private use, but it may cause difficulty on update comfy.
-- FlipStreamSaveApiWorkflow, FlipStreamRunApiWorkflow, FlipStreamSetState, FlipStreamGet nodes are useful to separate workflow to avoid OOE, because comfy keeps cache on each workflow and the cache take up large memory. FlipStreamGetState, FlipStreamGetParam, FlipStreamGet nodes have independent cache system, it can bridge any data on workflows.
