Ib py311 fixes

[goodboy]

So more or less this started as a set of patches to get py3.11 working in general despite there being some weird differences with asyncio.wait() and usage of it in the ib backend, but now it also includes a buncha fixes which are part of getting things working more properly on nixos. There might also be some rando fixes that need to get backported to other upstream devs branches that I'll detail below.

Currently the diff is against #528 but likely to change substantially; think of this as the dev dev dev branch 😂
