Ciborium replaced with bincode, and pacwrap-agent attained UX parity
- Refactored libalpm events into their own module - Agent parameters are acquired via a temporary file attached to the container (Still TODO: Provide a shared communication channel) - filesystem state files now contain magic values with file header verification - Miscellaneous tidy up work
