Replace date annotation to xsd:dateTime instead of xsd:string

[anitacaron]

• Add post process in the pipeline to change the range in date type annotations.
• Add QC to verify all annotations related to date use xsd:dateTime range

I tried changing the datatype to xsd:date and xsd:dateTime. The dates are still output as strings.

Support for datatypes other than string is still an open issue: INCATools/dosdp-tools#136
