/**
* The serialization version of a token.
*
* While the major/minor/micro versions are represented as `Int` at runtime,
* note that the serializer treats them as unsigned integers, so their range is
* 0 to 255.
*
* We must increment major whenever there are incompatible structural changes on the part of the core library:
* 1. changes to secret part structure
* 2. change to secret encryption algorithm,
* 3. change token signing algorithm
* 4. change to keyId -> key calculation
* Changes 2-4 could come from authentication library or if we overwrite the default values.
