  1. Change :appearance field in Autumn.Theme from string to atom

Before:

appearance: "dark"

After:

appearance: :dark
  1. Move text decoration fields into Autumn.Theme.TextDecoration

Before:

The struct had flat fields in %Autumn.Theme.Style{}:

%Autumn.Theme.Style{
  fg: "#ffffff",
  underline: true,
  # ...
}

After:

The struct now uses text_decoration:

%Autumn.Theme.Style{
  fg: "#ffffff",
  text_decoration: %Autumn.Theme.TextDecoration{
    underline: :solid,
    strikethrough: false
  }
}
