wasm_exec is a Wasm-powered, sandboxed implementation of exec() for safely running dynamic Python code

There are number of use-cases emerging that require arbitrary code execution, often code that is generated by LLMs (Large Language Models) like ChatGPT. This can enable some really cool functionality - like generative BI or website generation - but also introduce a massive security flaw if implemented via eval() or exec(). This is because arbitrary code can be executed using these methods. In a worst case scenario, exec'ing arbitrary code could enable some to rm -rf / your entire server!

This library intends to provide a secure method of executing arbitrary Python code to empower LLM-based code generation. This was originally intended to be a direct PR to Langchain but given that the problems with exec() extend to the entire Python ecosystem, it was decided that it would be better as a standalone package.

Given the love for Wasm on HN, I thought some folks might be interested,and I'd love additional feedback or contributions to the code base.
