[PR] Use unsigned element count when parsing EscherArrayProper ty [poi]

jmestwa-coder opened a new pull request, #1116:
URL: https://github.com/apache/poi/pull/1116

   ## Summary
   
   Use an unsigned element count when parsing `EscherArrayProperty`.
   
   ## Changes
   
   * Replace `LittleEndian.getShort()` with `LittleEndian.getUShort()` when reading the array element count (`nElems`) in `EscherArrayProperty#setArrayData`.
   * Align parsing behavior with the existing unsigned accessors in the same class.
   * Ensure values in the full unsigned range (`0-65535`) are interpreted correctly.
   
   ## Why
   
   * The element count field is treated as unsigned elsewhere in `EscherArrayProperty`.
   * Reading the field as a signed value can misinterpret counts greater than `32767`.
   * This creates inconsistent behavior between parsing and subsequent access to the property data.
   
   ## Tests
   
   * Added a regression test covering an element count larger than `32767`.
   * Verified that the parsed complex data size is calculated correctly using the unsigned value.
