Consistent behaviour for array data types

[JakobVogelsang]

As I user of this library, I want the function insertSelectedLNodeType to insert data types that are of type isArray correctly. Acc. to the standard, this means that on this SDO or DA there must be a count attribute indicating what the size is of. Count could be an integer or a string reference to the sibling data that defines the array size.

As discusses in this tissue https://iec61850.tissue-db.com/tissues/1647 and https://iec61850.tissue-db.com/tissues/1648 the usage of count as an integer is deprecated and as we work with NSD files we should not do that. Instead we should use the sizeAttribute attribute in the NSD file to auto set count.

Requirements:

• if there is a NSD element with the attribute isArray add a count attribute to the corresponding data
• count shall be what is described with the attribute sizeAttribute in the same CDC definition

Examples:

<CDC name="HWYE" ...>
...
<SubDataObject name="phsAHar"
      type="CMV"
      descID="IEC61850_7_3.CDCAnalogueInfo::HWYE.phsAHar.desc"
      presCond="M"
      isArray="true"
      sizeAttribute="maxPts"/>
... 
<DataAttribute name="maxPts"
      fc="CF"
      type="INT16U"
      dchg="true"
      descID="IEC61850_7_3.CDCAnalogueInfo::HarmonicMeasurandCDC.maxPts.desc"
      presCond="M"/>
...
</CDC>

results in

<DOType cdc="HWYE" id="....">
    <SDO name="phsAHar" type="..." count="maxPts" />
    ...
    <DA name="maxPts" bType="INT16U" fc="CF" dchg="true" />
</DOType
