Browser RPC layer for Univer main-thread and worker communication.

```typescript
// [!code word:UniverRPCMainThreadPlugin]
// [!code word:IUniverRPCMainThreadConfig]
import type { IUniverRPCMainThreadConfig } from '@univerjs/rpc'
import { UniverRPCMainThreadPlugin } from '@univerjs/rpc'

const config: IUniverRPCMainThreadConfig = {
  workerURL: new URL('./worker.js', import.meta.url),
}
univer.registerPlugin(UniverRPCMainThreadPlugin, config)
```

`workerURL` is required when the main-thread plugin starts. Build the following worker entry separately and point `workerURL` to its output.

```typescript
// [!code word:UniverRPCWorkerThreadPlugin]
import { UniverRPCWorkerThreadPlugin } from '@univerjs/rpc'

univer.registerPlugin(UniverRPCWorkerThreadPlugin)
```

## IUniverRPCMainThreadConfig

```ts
export interface IUniverRPCMainThreadConfig {
  workerURL?: string | URL | Worker
}
```

## IUniverRPCWorkerThreadConfig

```ts
export interface IUniverRPCWorkerThreadConfig {
}
```
