replace cims:dataType with appropriate RDF/XSD datatypes

[VladimirAlexiev]

As per #41,
cims:dataType cim:String are replaced with rdfs:range xsd:string etc.
So we should delete the definitions of these terms (these nodes with all their properties).

This query returns 36 different cims:dataType:

PREFIX cims: <http://iec.ch/TC57/1999/rdf-schema-extensions-19990926#>
PREFIX cim: <https://cim.ucaiug.io/ns#>
select ?type (count(*) as ?c) {
  ?x cims:dataType ?type
} group by ?type order by desc(?c)

Most of them are QuantityKind or XSD datatypes, but we need to examine the rest and decide:

• profcim:IRI -> xsd:anyURI
• profcim:StringIRI : string or IRI
• rdf:LangString -> rdf:langString (have issue already)
• md:Statement??

• Use Standard Datatypes #74 shows the mapping table.
• It maps and deletes the following profcim props:

dt	c	xsd
profcim:URL	0	xsd:anyURI	Not used, but mapped for completeness
profcim:IRI	3	xsd:anyURI
profcim:StringFixedLanguage	1	xsd:string
profcim:StringIRI	3	xsd:string
