feat: log in with soulseek-rs's own client major version (176) (#13)

The Login message hardcoded SoulseekQt's major version 157, so the
server could not tell soulseek-rs apart from the official client. The
protocol document now reserves a unique major version per project, so
claim 176 and send it via a new ClientVersion on ClientSettings.

Clients and bots built on the library keep major 176 and pick their own
minor version (default 1); the reference CLI/TUI logs in with minor 100.
