Make the UI generate configs that use submapping for axises values

[skfoo]

If you use the GUI to create the yaml file, it generates an axis using the shorthand form like this,

Prompt Replace 1: <lora_add_detail> = <lora:add_detail:0.0>,<lora:add_detail:0.25>,<lora:add_detail:0.5>

If you want to upgrade this to use a mapping so you can add labels, it's very tedious to manually convert it. I had to convert multiple axises so I could give the values proper names (to deal with what I wrote about here: #50 (comment)). Fortunately I came up with a regex to use with search & replace in a text editor that did most of the work. Unless I'm overlooking something simpler, this is what I needed so the axis had a name with labels for each value:

  add_detail:
    title: add_detail
    values:
      d0.0:
        title: detail 0.0
        params:
          prompt replace: <lora_add_detail> = <lora:add_detail:0.0>
      d0.25:
        title: detail 0.25
        params:
          prompt replace: <lora_add_detail> = <lora:add_detail:0.25>

It'd be great if the GUI would output that form instead by default.
