Got a serverless Nostr client going this morning.

This was blocking me on a project I'm working on for http://nostr.money. #FeelsGoodBro

FYI the stack was: AWS Gateway triggering a lambda function to temporarily spin up an ECR-hosted Docker image.

Needed to containerize the solution because the secp256k1 python library was driving the raw python implementation over AWS Lambda's code+layer size limit.
