        Set the feature tags to enable on the font.

        Parameters
        ----------
        features : list of str, or tuple of str, or None
            A list of feature tags to be used with the associated font. These strings
            are eventually passed to HarfBuzz, and so all `string formats supported by
            hb_feature_from_string()
            <https://harfbuzz.github.io/harfbuzz-hb-common.html#hb-feature-from-string>`__
            are supported. Note though that subranges are not explicitly supported and
            behaviour may change in the future.

            For example, if your desired font includes Stylistic Sets which enable
            various typographic alternates including one that you do not wish to use
            (e.g., Contextual Ligatures), then you can pass the following to enable one
            and not the other::

                fp.set_features([
                    'ss01',  # Use Stylistic Set 1.
                    '-clig',  # But disable Contextural Ligatures.
                ])
