added JSON and YAML in the article on “data logger” / data formats on the English Wikipedia

• https://en.wikipedia.org/wiki/Data_logger#Data_formats

I wonder, whether this modifications will find mercy in the eyes of the “article surveyors”.

• JSON: I attended a presentation given by a member of Pivotal.io, telling of a data logger device, that they use in a project, that emits JSON
• YAML: a huge international web warehouse exchanges its data with its logistics partners in YAM – that is EDI genuine homeland. I personally and directly know of business going on like that.

Yes, I should have quoted both of them, when I added the 2 to the article. But then – what serious proof do I have?
