Add support for polygon padstack pads

[pyAnsysUser]

Description of the feature

Presently, a polygon shaped pad within a padstack is not handled in pyedb. I would like to see support for this in a future update

Steps for implementing the feature

No response

Useful links and references

Here is an example demonstrating the issue I encounter:

output_path = r'testOutput'
temp_folder = os.path.join(output_path, 'new_test_folder')
if not os.path.isdir(temp_folder):
    os.mkdir(temp_folder)
else:
    shutil.rmtree(temp_folder)
    os.mkdir(temp_folder)

file_path = r'\test_inputs\PolyArtwork.aedb'
edb = Edb(file_path, edbversion='2024.1')
lyr = edb.stackup.layers['signal_1']
lyr.name = 'TOP'
edb.save_edb_as(os.path.join(temp_folder, 'output.aedb'))
edb.close()

In the original file, PolyArtwork.aedb.zip, open the graphical viewer to see 4 padstacks; two on the left are polygon point defined shapes, the two on the right are a circle/square and a rectangle.

After the layer name change, the polygons are not found in the database, however the circular and rectangular pads are.

Maybe, this is the same as #489
