Reorganize parts libraries (#492)

Adds sub-package structure to the parts library. Refactors
pyproject.toml to auto-discover packages and include package data by
extension.

Breaks some of them into vendor_parts (implementations of
abstract_parts, including the JLC library) and circuits (which are
solely composed of abstract parts).

A follow-on PR will break up electronics_model (separating out
electronics_interfaces) and abstract_parts (moving stuff into circuits)
