v1.14.0

NOTE: This release changes metadata stored in the .fw files in a way that
doesn't affect any functionality, but is visible in the firmware UUID
construction. In other words if you use the exact same inputs with this version
of fwup and an older version, you'll get different UUIDs. This was done to
prevent compatibility issues between fwup versions when parsing metadata that
needed to change from being an integer to a string for holding very large
numbers.

• Improvements
  • U-Boot environment blocks can now be written to offsets beyond 2 GB. Prior
    versions would likely silently fail
  • Don't unconditionally double quote strings in the metadata file. This allows
    more flexibility in changing fields to strings when they go beyond what's
    supported by libconfuse while not breaking backward compatibility.
