Addition of UUID field – open for discussion

[davous267]

Suggestion by Paul Sorensen (@ncadpaul):

It looks like the Id field is a number locally unique to file; could an optional string encoded UUID (see https://datatracker.ietf.org/doc/html/rfc4122) be added per object? For example: “uuid" : "2948446b-6213-44ba-b81f-c4e5f7dab2eb”.
For example, this would assist in mapping from UNF to my apps format for round trip processing in apps like OxDNA / OxView that might support it going forward; otherwise, I have to generate a separate file to track that information.

A possible solution in the current version of UNF:

Utilization of misc field by adding something like uuidMap of a form "id" -> "uuid" where id is a local unique ID in unf, UUID is desired UUID.

Is there a common desire for this feature? How this should be handled on a design side, etc.? Opinions welcome.
