Update pyright

[ItsDrike]

This PR performs a long-awaited pyright update & fixes all of the issues that have accumulated over time.

The most notable change here is to the pinger.py and querier.py files, where the old classes were turned into data-classes, with a new base class, to better handle the weird sync -> async inheritance. This approach still requires type ignores in the method overrides, but it is a lot more sensible and clean.

Note that I've added a "disableBytesTypePromotions": false pyright setting, which was newly introduced (well, at least newly compared to the version we're updating from) and re-introduces the old technically type-incorrect approach that treats bytearray as a subtype of bytes. It would be possible to fix this instead, but it would affect a lot of the existing code. If desired, this can be done at later time.

Finally, on top of just the necessary changes to make pyright pass, I have made a few slight improvements to typing in some places, these are generally very minor.

Superseds & closes: #923

Thanks for picking this up. I forgot about pyright update PR that I self-assigned a while back.
