Instead of `presets.foo.preset` -> `presets.foo.builtin`

The naming of the config option is confusing, especially with the new top-level presets.

builtin = "pomororo" | "52/17" or something along those lines may be a better alternative.

I definitely agree with you. Thanks for the suggestion.

I refactored the API, and made it way more simple. There is no more builtin presets, to avoid any trouble. Name also aligns with other Pimalaya tools (it is now account, not preset anymore). I did not yet changed the doc, nor the changelog, but you can have a look at the new config.sample.toml.
