[platform.logsDropped] Unable to process 1000 logs for each invocation

Hey team!

We're experiencing an issue while dealing with the Telemetry API when the function has 1k logs.

At some point, we're receiving a `platform.logsDropped`, likely because we're not succeeding to process the payload sent in a timely fashion (this is what I've understand from [the doc](https://docs.aws.amazon.com/lambda/latest/dg/runtimes-logs-api.html))

To make it easier [I've attached a PR](https://github.com/aws-samples/aws-lambda-extensions/pull/89) with a full reproducer. If you invoke the function 10-30 times, you'll see a `[dispatcher:Dispatch] LOG DROPPED!` meaning that we have indeed received a `platform.logsDropped`

I've also tried different buffering options (playing with `timeoutMs `, `maxBytes ` and `maxItems `) without any luck.

Thanks!
Max

添付された PR とその完全な再現手順から始め、`[dispatcher:Dispatch] LOG DROPPED!` メッセージに関連する Telemetry API の経路を追跡します。文書化されているバッファリングオプションを使って関数を 10～30 回呼び出し、`platform.logsDropped` が発生しなくなったことを確認して結果を検証します。
