Package Semaphore: - simplify the base semaphore (context, max wheight...) - merge semaphore with progress instance - extend semaphore with context interface Package Progress - rework MPB instance - bump MBP to v8 - integrate MPB into Semaphore to use a same instance for sem / mpb - rework bar to simplify it - bar is now also a semaphore & context - allow to create bar with custom options
