[PATCH 2/4] CVE-2022-26307 make hash encoding match decoding

Seeing as old versions of the hash may be in the users config, add a
StorageVersion field to the office config Passwords section which
defaults to 0 to indicate the old hash is in use.

Try the old varient when StorageVersion is 0. When a new encoded master
password it set write StorageVersion of 1 to indicate a new hash is in
use and use the new style when StorageVersion is 1.
