Rename nym-lp-speedtest to nym-lp-client and fix KCP bug

- Rename crate from nym-lp-speedtest to nym-lp-client
- Fix KCP bug: add driver.update() call before fetch_outgoing()
  Without update(), KCP never moves segments from snd_queue to snd_buf
- Update CLI name, about string, and user agent to match new name
