Release 0.14.1

Fixed

• Encoding a struct type (a map type with a __struct__ field, e.g. from Elixir) with non-map data (a string, integer, list, or atom) crashed with a raw badmap error instead of returning {error, [spectra:error()]}. Plain map types, list types, record types, and decoding were unaffected — only the struct branch of to_json/4 was missing its is_map/1 guard.
