Add exception handlers for Polygon and Locale methods

[vietnguyengit]

Please feel free to ignore/add new commits to the PR if you don't think it's useful, I won't put more efforts to this PR since the problems have been solved for us;

Missing the exception handlers blocking us from processing large number of records;

sample code to reproduce:

# Define the queries to search for records using GCMD Keywords
gcmd_query_lower = PropertyIsLike("AnyText", "%gcmd%")
gcmd_query_upper = PropertyIsLike("AnyText", "%GCMD%")
gcmd_query_full = PropertyIsLike("AnyText", "%Global Change Master Directory%")

# Define the query to exclude records containing 'AODN Discovery Parameter Vocabulary'
aodn_exclude_query = PropertyIsNotEqualTo(
    "AnyText", "AODN Discovery Parameter Vocabulary"
)

# Combine all queries using Or and And filters
combined_gcmd_query = Or([gcmd_query_lower, gcmd_query_upper, gcmd_query_full])
final_query = And([combined_gcmd_query, aodn_exclude_query])

# Connect to the CSW service
csw = CatalogueServiceWeb(
    "https://catalogue.aodn.org.au/geonetwork/srv/eng/csw?request=GetCapabilities&service=CSW&version=2.0.2"
)

you might want to use outputschema param within csw.getrecords2() method to be: http://standards.iso.org/iso/19115/-3/mdb/2.0
