Pypsi 2.0 Roadmap

[ameily]

Pypsi has evolved and I've noticed there's several assumptions I made that are not necessary anymore. For Pypsi 2.0, which will have breaking API changes, I'd like the following:

• Simplify wrapping the standard streams. Right now, there's a couple classes that handle stdout and stderr (thread local proxy, win32 ansi stream, etc). Multiple places call sys.stdout._get_target(), and I'd like to really remove instances where protected API calls are used.
• Remove unnecessary functionality such as ANSI stream formatting, format functions (title_str), etc
• Support dynamically determining stream width
• Add type annotations
• Redesign and simplify topic/help system
