add type stubs

[zzstoatzz]

adds a python/libipld to house the .pyi file and the __all__

following the _{module_name} pattern that I use (and got from pydantic-core), note that maturin develop knows about the module-name set in pyproject.toml

let me know if there are any python type translations I messed up!

so uv sync gives you all you need for maturin develop --uv

gentle ping for whenever you have a moment to look @MarshalX - I know there's probably more pressing things so I'll check back later 🙂

That's an amazing job, thank you!!

I saw it already but did not comment immediately because this PR also integrates UV. I am still thinking about it but if we want to speed up it let's just include .pyi file :)

[zzstoatzz]

i don't think anything (else, after removing uv.lock) here is uv specific, for example dep groups are a python thing but I can remove it if you want (it shouldn't affect pip setups or anything about your distribution metadata like an extra would)

EDIT: doh the lockfile! duh, let me remove that

not sure if related to my changes (i suspect not) or if these just have high variance

@zzstoatzz that's just a noise from small bechmarks. ignore it :)
