Function someipRequest

someipRequest(
opts: SomeipScriptSendBase,
timeoutMs?: number,
): Promise<SomeipMessage>
Send a REQUEST and await the matching RESPONSE or ERROR from the vSomeIP client in the main process.
Parameters
- opts: SomeipScriptSendBase
  Service / instance / method / payload and optional channel, versions, and request_service major/minor.
- timeoutMs: number = 1000
  Maximum wait time in milliseconds for the response (default 1000).
Returns Promise<SomeipMessage>
The decoded SomeipMessage for the response (payload as Buffer).
Throws
When the device is unknown, the service is unavailable, or the stack times out waiting for a reply.

Remarks
Mirrors the UI / IPC path ipc-send-someip for REQUEST: performs request_service then sendRequestAndWaitResponse.
Example
```
const resp = await someipRequest(
  { service: 0x1234, instance: 1, method: 0x6001, payload: [0x01] },
  2000
)
console.log(resp.returnCode, resp.payload)
```
