Use SyncByteStream instead of ByteStream

[seowalex]

The synchronous version of AsyncByteStream is actually SyncByteStream, not ByteStream:

class ByteStream(AsyncByteStream, SyncByteStream):
    def __init__(self, stream: bytes) -> None:
        ...

    def __iter__(self) -> Iterator[bytes]:
        ...

    async def __aiter__(self) -> AsyncIterator[bytes]:
        ...

class SyncByteStream:
    def __iter__(self) -> Iterator[bytes]:
        ...

    def close(self) -> None:
        ...

Thanks for the PR 🙏 right, we should use SyncByteStream not the ByteStream...
Can we also have a changelog please?
