Enhancement: Retain comments and structure in TOML file

Good day Christian.

Yeah, it's another one of my crazy ideas: Load the TOML file as-is, keep it in memory like this. When you need to change an option, search and replace the line that has the option; new options go at the end. Ie. Preserve the file with comments and ordering.

Kinda annoying to code if you've got nothing of the sort right now, but it would be nice-to-have.

Thanks.
Best Regards,
