Rewrite LambdaLog using TypeScript #64

Description

I want to rewrite LambdaLog from the ground up using TypeScript. This will provide a few benefits:

• Type definitions will live in the repo instead of using an unreliable third-party source.
• Type safety will help alleviate some of the checks being executed within the app, thus reducing complexity and code.
• Ability to compile to both ESM and CommonJS automatically so both can be supported.
