Jack Grigg de78186503 Store anchors as pallas::Base instead of [u8; 32] 
This matches what we store in `MerklePath`, and better enforces the
required type.

Jack Grigg 497f7e0b86 Remove bundle::Unauthorized type 
It is being replaced by context-specific unauthorized or

Jack Grigg 5ec65c5d2a Add a mutable context to Bundle::{try_}authorize 
This enables us to work around lifetime restrictions on e.g. the
randomness source at signing time, where it is needed for both
per-Action and Bundle-level signatures.
