Change log for UMBRELLA_IP

Date	Changes
2025-10-07	Enhancement: - Modified the conditional check for mapping `column15` to parse correctly for `event.idm.read_only_udm.security_result.about.file.sha256` UDM field. - `event.idm.read_only_udm.principal.resource.attribute.labels`: Newly mapped `column3` raw log field with `event.idm.read_only_udm.principal.resource.attribute.labels` UDM field. - `event.idm.read_only_udm.additional.fields`: Newly mapped `column4`, `column5` raw log fields with `event.idm.read_only_udm.additional.fields` UDM field. - `event.idm.read_only_udm.network.ip_protocol`: Newly mapped `column11` raw log field with `event.idm.read_only_udm.network.ip_protocol` UDM field. - `event.idm.read_only_udm.target.ip` and `event.idm.read_only_udm.target.asset.ip`: Newly mapped `column15` raw log field with `event.idm.read_only_udm.target.ip` and `event.idm.read_only_udm.target.asset.ip` UDM fields. - `event.idm.read_only_udm.security_result.rule_name`: Newly mapped `column22` raw log field with `event.idm.read_only_udm.security_result.rule_name` UDM field. - `event.idm.read_only_udm.principal.ip` and `event.idm.read_only_udm.principal.asset.ip`: Newly mapped `column13` raw log field with `event.idm.read_only_udm.principal.ip` and `event.idm.read_only_udm.principal.asset.ip` UDM fields. - Added conditional checks involving "pattern_unmatched" and "pattern_not_matched" data fields before the final merge of the `security_result` variable into `event.idm.read_only_udm.security_result` UDM field. - Refactored parser logic to handle cases where `column3`, `column4`, and `column5` do not contain IP addresses by mapping them to alternative UDM fields. - Refactored parser logic to extract and map an IP address from `column13` to principal IP fields. - Refactored parser logic to extract and map an IP address from `column15` to target IP fields when it does not represent a SHA256 hash.
2025-08-07	Enhancement: - Remove uneccesssary initialization of variables to correctly populate the fields.
