Support Lelo F1s V3 as Harmony protocol

[aabbccddeeeeee]

Summary

• Move F1SV3 matching from the F1S V2 protocol to the Lelo Harmony protocol
• Add an F1SV3 Harmony protocol variant that sends a zero pattern when stopping vibration
• Add protocol tests for F1SV3 command encoding

Root cause

F1SV3 advertises similarly to the existing F1S V2 entry, but tested hardware exposes Harmony-style control characteristics and does not respond to the F1S V2 motor payloads. The device vibrates with Harmony-style writes to the tx characteristic and requires a different zero-speed stop payload.

Testing

• cargo test -p buttplug_server lelo_harmony::test
• cargo test -p buttplug_tests --test test_device_protocols lelo_harmony_protocol
• cargo test -p buttplug_tests --test test_device_protocols lelo_f1s_v2_protocol
• Manual test with LELO F1S V3 on macOS/Intiface Central

I wonder if my v3 is of an earlier generation that did support the original control structure too...
