XADD/XREAD binary values / wrote binary, read string / Redis streams

[slavafomin]

Hello!

Thank you for this great library!

I'm working with Redis streams.

However, when I send some values in binary form to XADD I receive them back as string when I do XREAD.

When I try to use the xreadBuffer() method instead, it returns everything as buffers (even the keys).

There should be a way to send some values in string, some in integer and some in binary. It shouldn't treat everything as either string or buffer.

Thanks!
