[Suggestion] Associate variables with attempt id instead of entire splits file

[TheTaraStark]

Currently, most runners have separate splits files for different variables in the same category. I'd like to suggest associating variables to the <Attempt id> tag so runs with different variables can all coexist on the same file.

This would simplify splits file management for runners, and enable easier variable switching for folks who play multiple variables in a same category.

In the future, this could also allow for new comparison opportunities - runners could choose to compare against runs with some of the same variables as the current run, all of the same variables, all runs regardless of variables, etc. Total playtime in a certain set of variables could easily be compared to play time across all variables.

Associating variables with <attempt id> seems (on the surface) like a simple solution that could also easily retain backwards compatibility, and allow for the creation of a tool to combine splits files with different variables into the new format (though the latter would probably be a separate project).

Would love to hear thoughts on feasibility, other possible implementations with similar outcomes, etc.

This is actually an incredibly good idea! I would love the ability to be able to combine and easily switch between unique comparisons far more easily. I second this possible implementation
