fix: Fix window build bug caused by Instant resolution. (#1884)

* feat: Split writer into connection worker and wrapper, this is a
prerequisite for multiplexing client

* feat: add connection worker pool skeleton, used for multiplexing client

* feat: add Load api for connection worker for multiplexing client

* feat: add multiplexing support to connection worker. We will treat every
new stream name as a switch of destinationt

response from offset

* feat: some fixes for multiplexing client

* feat: fix some todos, and reject the mixed behavior of passed in client or not

* feat: fix the bug that we may peek into the write_stream field but it's
