Added two classes:
* BlockPair()
* Track source/dest pair specific data
* update_progress() method for its own data
* RecoveryState()
* Track BlockPair objects and overall state
* update_progress() method for overall data
Reasons:
* Code readability
* Better status updates, code currently split between:
* get_recovery_scope_size()
* resume_from_map()
* update_progress()
* Functions that should probably be merged into other functions:
* get_recovery_scope_size()
* set_dest_image_paths()
* check_dest_paths()
* Logic that needs to be cleaned up:
* Calculating overall recovery size
* Pass "Done"ness and status strings need separated
* Pass "Done"ness at the device and overall levels
* Updating output for side pane status display
