gh-16429 introduced support for an iterable of separators in Stream.readuntil. Since bytes-like types are themselves iterable, this can introduce ambiguities in deciding whether the argument is an iterator of separators or a singleton separator. In gh-16429, only 'bytes' was considered a singleton, but this will break code that passes other buffer object types. Fix it by only supporting tuples rather than arbitrary iterables. Closes gh-117722.
