[ENHANCEMENT] - Add `qcio_version` field that auto-fills for all objects upon first creation

[coltonbh]

QCIOBaseObject(...):
    .qcio_version
    ...

Have this auto-population on the first instantiation (using field_validator or model_validator) and then have it respect the saved value for any future .open() or re-instantiations of this value is already defined.

This will help future-proof data structure upgrades because end users will always know what version of qcio they need to open and interact with their saved data.
