Describe the bug

This might be tangentially related to #48.

For my config I don't like names or RGB to be globally enabled, but for css filetypes these can be helpful.
So I figured the css = true option would be a concise way to allow those features to be limited to only css filetypes.

This does not work, requiring the user to explicitly override the disabled options defined in user_default_options.

setup = {
  user_default_options = {
    RGB = false, -- annoying in some contexts
    names = false, -- annoying in some contexts
    mode = "background",
  },
  filetypes = {
    "*", -- Use default options for all other filetypes

    -- This should be sufficient to ensure all css features are enabled
    -- css = { css = true },

    -- Unfortunately, these settings need to be explicitly enabled to override user_default_options
    css = { css = true, names = true, RGB = true },
  },
}
