Large request payload crashing API

I am having the exact same issue described here: https://github.com/googleapis/nodejs-logging-bunyan/issues/14

Throughout the codebase, occasionally (and accidentally) I am logging very large entries, and encountering an exception which crashes the server:

```tsx
Error: 3 INVALID_ARGUMENT: Request payload size exceeds the limit: 10485760 bytes.
File "/workspace/node_modules/@grpc/grpc-js/build/src/call.js", line 31, col 19, in callErrorFromStatus
const error = new Error(message);
File "/workspace/node_modules/@grpc/grpc-js/build/src/client.js", line 192, col 76, in Object.onReceiveStatus
callProperties.callback((0, call_1.callErrorFromStatus)(status, /*callerStack*/ ''));
File "/workspace/node_modules/@grpc/grpc-js/build/src/client-interceptors.js", line 360, col 141, in Object.onReceiveStatus

File "/workspace/node_modules/@grpc/grpc-js/build/src/client-interceptors.js", line 323, col 181, in Object.onReceiveStatus
'{snip} ener === void 0 ? void 0 : interceptingListener.onReceiveStatus) === null || _b === void 0 ? void 0 : _b.call(interceptingListener, status);
File "/workspace/node_modules/@grpc/grpc-js/build/src/resolving-call.js", line 94, col 78, in

File "node:internal/process/task_queues", line 77, col 11, in process.processTicksAndRejections
```

I am using the logging-bunyan Express middleware as follows:

```tsx
const { logger: gcpLogger, mw } = await lb.express.middleware({
logName: "api-" + process.env.FLY_APP_NAME,
level: "debug",
defaultCallback: (err: any) => {
try {
if (err) {
console.error("Error occured with logger.", err)
Sentry.captureMessage(err, { level: "error" })
}
} catch (_err) {
console.error("Error occured with logger in try/catch blog.", _err)
Sentry.captureException(_err)
}
return true
},

// GCP should truncate the message down to 200kb.
// See https://github.com/googleapis/nodejs-logging/pull/607.
maxEntrySize: 200000,
})

```

It doesn't look like I'm able to pass in the arguments to this middleware as per the solution described here: https://github.com/googleapis/google-cloud-node-core/issues/480

maxEntrySize also doesn't seem to properly truncate.

Ideally, I don't care as much about truncating; I just want to properly handle the exception and not crash the server whenever I inadvertently attempt to log a massive entry.
