tdf#114821 import complex data labels in bar chart

* import static text & fields:
   VALUE, SERIESNAME, COLUMNNAME
* text is formatted
* DataPointCustomLabelField with field type
  (DataPointCustomLabelFieldType) was introduced.
* text can have many portions & multiple lines
* unit tests for import data labels with formatting

Not implemented: CELLREF field support which needs
importing some additional data from extLst

Shows custom text as a label for data points.
