Requires boto3 as a dependency?

[Tethik]

I get the following error when trying to invoke locally (i.e. serverless invoke local). However deployed on aws it works fine, presumably because boto3 is already installed as a system package.

Fixed by installing boto3. Should it be required as a dependency though?

So, we use SQS as a transport to avoid having our Lambda function deployed to VPCs. I think lambda functions always come with boto3 which is probably why we missed this. Adding boto3 as a dependency seems pretty safe.
