ConsumptionCount to support a xsd:float as count or share

[JuergenGrupp]

ConsumptionCount has the audienceCount property typed as a rdfs:Literal. It should also support a count or share expressed in digits, like demonstrated in the examples of the definition:

• a 72% market share of French viewers aged 14 to 29 for the football world cup final 2022
• 18.7 million live stream views of the funeral of former pope Benedict in Europe
• 36973 views of the youtube-video "Tom Hanks had an ICONIC chat with the Queen" from BBC's "The One Show" 6 months aber publishing
  Proposal:
  Add a property count of type xsd:float to represent either integers (36973 views), rounded integers (18,7 million views) or shares (72% market share). Use hasObjectType to classify the meaning and the unit.
