[docs] [issue25916] wave module readframes now returns bytes not str

[Martin Panter]

Martin Panter added the comment:

Two of the changes don’t seem right to me; see the review. In the other two cases, IMO “string of bytes” is a reasonable description of :class:`bytes`, but being explicit is better.
