[remove duplicates] data / data item & data set / data set

through the import of IAO we have duplicate definitions:

dataset:

• HDO_00001037
• IAO_0000100

The HDO definition is shorter and generally favoured. Remove IAO_0000100

data / data item

• HDO_00000009 (superclass set)
• IAO_0000027 (superclass information entity)

Remove IAO_0000027 and adjust definition of HDO_00000009 to: definition "An information entity which consists of quantitative or qualitative representational entities encoded as signs, symbols, markings, values, or patterns on or in any medium."@en
