[Proposal] The NEF frame nef_nmr_meta_data history should include uuids

[varioustoxins]

The nef_nmr_meta_data frame includes a uuid but doesn't include it in the _nef_run_history loop. It is suggested that this is included in the _nef_run_history loop as shown below using the tag _nef_run_history.uuid. This would allow files to be tracked as they are modified.
