Adds per entry nutrition

I didn't realize this is also here so I'll leave the same comment I left on the enhancement request:

So I came up with something but I have no clue if its actually good. This took me a few days to figure out with a ton of trial and error. I have no clue if this is how dart likes to format its code. Also I couldn't get VSCode to properly load the project without updating the pubspec and the settings.json so I made changes to them on my side and removed them from the git tracking and I think that will keep it in line with your settings but I'm not sure if that was the correct choice tbh. I will submit a pull request for you to review. If it doesn't cut it its fine I honestly have no clue if this is memory safe or follows best practices.

Also some other things, I decided on the static table version for mine since I thought that would work better if the only point of change was the quantity and it should update automatically on saves
