catch up of #107

Broad Concerns:

• various code results in different exceptions being raised in unexpected cases. for example, an AssertionError if an object is None where previously a TypeError would have been raised where we take the len() of the object.
• hinting around internal complex stack-related activities that... i should probably mostly accept failure on and ignore

Draft For:

• TODO:s
• naming suggestions raised in more mypy #125 (comment)
• reviewing explicit concerns above

In chia_rs .as_atom() was changed to raise when .atom was None. If we make that same change here, it will simplify a lot of areas it seems.

Thanks for looking.
