Subject: [PATCH] fix: use tuple form for SpeechGroupSpanData __slots__

__slots__ was assigned the bare string "input", which Python treats as
an iterable of single characters, creating slots i, n, p, u, t instead
of a single input slot. Every other SpanData subclass uses tuple form;
align this one to ("input",).
