Implement ToPyObject for [T; N]

[PigeonF]

It seems like this was forgotten to implement (unless there was a good reason not to implement this, which I did not find in my quick search).

CI failure is unrelated and affects main as well ATM.

Thanks!

I'm not sure why this was missing. I suppose in most cases, like when calling the method on an array, it can find the &[T] implementation - but inline-python uses it in a generic context where this does not work.

impl<T, const N: usize> was only stabilized in rust 1.51, i'd have loved to have done this earlier! i'm surprised though we didn't have any impl for small slice lengths, since for tuples we have the tuple_conversion macro which implements tuples up to size 12.

It's already guarded by a feature flag, which is set by build.rs depending on version. rustversion is not used as a non-dev dependency.

Yep I think this was just an accidental omission 👍

Rebasing on main should fix the 3.11 error

Thanks!
