feat: optimized save in neovim and need reload the entire jupyter file.

[chaozwn]

The whole plugin is very useful。But when I save the file in neovim, I need the browser to choose whether to overwrite, save, etc. My hands do not want to leave the offer, I feel that this is very troublesome, can you optimize it？

Does this happen if you set auto_download_ipynb=false?

I think that you have a file test.ju.py in a folder, and Jupyter is running on the same directory editing test.ipynb, and when you save some process (could be jupynium or another plugin) is touching the ipynb apart from the FireFox. I'll need to investigate more.
