add occurrenceID to the Identification History extension

I reached out to @timrobertson100 and he asked me to pull this issue.

Like #136 , it would be useful to add occurrenceID to the 'Identification History` extension. This would be especially useful for the eDNA community, who are concerned about the ability to track taxonomic updates as reference databases improve. Likewise, it would give GBIF a structure to store taxonomic updates, if GBIF decides to reinterpret DNA sequences as a service to the community.

Tagging @tobiasgf, @ksilnoaa, @saarasuominen, @eboulanger, @MathewBiddle for awareness.

For eDNA identification history, would not adding materialEntityID make even more sense?

I can understand this, but while there is no core entity for Material and GBIF/OBIS only index Occurrence records I don't think it would be a practical approach. This is an example of something that the new data model will properly fix; i.e. distinguishing between events of organisms occurring (Occurrences), how they were detected/observed, the evidence (e.g. material / media etc) to support the claim and the relationships between entities. Knowing that is emerging and will use different schemas anyway, my feeling is occurrenceID is a pragmatic approach for now within the DwC-A structure.

@dagendresen I agree with Tim that this is a pragmatic solution for testing publishing models of data types like eDNA now, while we work toward the new data model. I look forward to being able to use materialEntityID as part of the new data model in the future.
