refactor(cli|exceptions): small update and clean up

[spencer-tb]

🗒️ Description

Primarily splits up exceptions.py into exceptions/, with no changes to code only a restructure:

exceptions/
├── __init__.py
├── base.py
├── block.py
├── eof.py
├── transaction.py
└── types.py

Additionally removes EOF exceptions from all clients minus evmone. These are simply copied over from evmone's exception so are pointless now. The aim is to reduce some bloat here.

Please comment with any other clean up suggestions.
