LyricsV-core

The core component of LyricsV.

Architecture

LyricsV uses IPC to communicate with the core. And inside the core, worker threads of different components use MessagePort to communicate with each other.

We encapsulated IPC and MessagePort into "events" inside the SerializedEventEmitter. Now the event list is shown below.
