[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
