this commit introduces a new `Body` combinator to the `http-body-util` library, `http_body_util::combinators::Fuse<B>`. this combinator is roughly equivalent to the `std::iter::Fuse<I>` iterator, which returns `None` after the inner iterator returns it once. while bodies *should* return `Poll::Ready(None)` indefinitely after reaching the end of the stream or returning an error, this combinator can help prevent further polling of an underlying body implementation, in the same manner that `std::iter::Iterator::fuse()` helps prevent an underlying iterator that might e.g. yield `Some(value)` after yielding `None`, or panic.
