Pyodide/Wasm Support

[dataphysician]

Issue
Hamilton is well-suited for in-browser execution via Pyodide/WebAssembly (Wasm), but its reliance on multiprocessing is a blocker since WebAssembly currently does not support traditional multiprocessing.

Request

• Identify areas where multiprocessing is used and explore alternatives within Pyodide’s single-threaded constraints.
• Assess any other Pyodide-specific adjustments needed for smoother operations.

Expected Outcome
Hamilton running in a Pyodide/Wasm environment, potentially with an alternative parallel execution model. If feasible, outline steps toward a production-ready WASM build.

(Note: Posted this in Burr thinking it was Hamilton. 🤷‍♂️)

@dataphysician thanks!

So currently https://github.com/DAGWorks-Inc/hamilton/tree/try-hamilton has some changes that make hamilton installable.

Ideas:

1. Figure out if we can determine whether we're in a WASM environment and not import multiprocessing and a few other things.
2. Create new package sf-hamilton-wasm that is a parallel branch we maintain and update specifically for wasm use.

My preference is for (1) but I haven't explored it at all.

Change should go out this week to enable default package to work under wasm.
