default to non-blocking (via sys::exec_background()), which feels like blocking, because we poll via poll_sys_proc_nonblocking(), which does sys::exec_status(proc, wait = TRUE) (waiting blocks the console, which is needed).
add message_type argument, which is consistent with rix_init() and with_nix() and internal helpers.
[x] with_nix()
addresses #181
overall simplifies external API of core rix functions and also makes them easier to use and predictable for the user. Same for internal helpers.
