`~/.local/share/io.github.armchairdevelopers.maxima` used by UI while `~/.local/share/maxima` is used by everything else

[p0358]

It seems that egui/eframe writes its app.ron for persisting app state into that folder, instead of where Maxima consciously places all of its other files.

It seems it's dictated by this:

    /// ### eframe
    /// On eframe, the `app_id` of the root window is also used to determine
    /// the storage location of persistence files.
    #[inline]
    pub fn with_app_id(mut self, app_id: impl Into<String>) -> Self {
        self.app_id = Some(app_id.into());
        self
    }

Not a big deal, but could be tackled at some point to reduce the mess left on the system (but it sounds like it might not necessarily be configurable currently, since I didn't find anything with a quick search, which'd be annoying).

If they want to make it non-configurable, then it's arguably an upstream bug to put it in ~/.local/share instead of ~/.local/state where Qt puts its automatically-generated UI state files for example.
