Make aws-sdk dependency optional

[eduardoboucas]

Hi! We use lambda-local in the Netlify CLI to provide a local environment for serverless functions. Unfortunately, having the AWS SDK as a dependency significantly contributes to our package size, despite the fact that we don't interact with it at all.

I understand that this is required by some of your users and we definitely wouldn't want to disrupt that, but I was wondering if you'd consider publishing a second package without this dependency to accommodate folks who don't need the AWS interaction and could benefit from a smaller payload?

If you're okay with this, I'd be happy to put together a PR with a workflow that automates this process, so that having this second package wouldn't mean additional overhead for the project maintainers.

Thanks in advance!

Hi, this sounds great, feel free to provide a PR anytime.

We only include aws-sdk because it is already included on AWS lambdas, but TBF we could just remove the dep entirely and ask people to download it themselves... If you have a better way that's cool too.
