Feature request: documentation for worker implementations in other languages

[tcwalther]

It would be fantastic if a documentation page existed that explained exactly the steps that a third-party library would have to implement to produce a compatible worker.

Use Case

Most ML or scientific code is written in Python. It would be phenomenal if I could trigger Python jobs using SolidQueue in Rails. The Python library would only need to implement a small subset of SolidQueue, enough to pick up a job and process it.
