Unable to upload to AWS Lambda due to size

Using the exact same code and setup from this repository, the final published zip file comes out to around 56MB. The unzipped folder runs around 63MB.

AWS Lambda Functions have a limit of 50MB for the zipped deployment package (https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-limits.html). 

Has anyone been able to successfully deploy this to AWS?
