[BUG] Sub-fields naming collision

[A-Gray-Cat]

What is the bug?
For example, if a log line contains two sub-fields that have the same name, direct query would ignore the top level fields and think both fields are duplicated. For example, the sql query below will return one field ip, with the top level fields stripped. The PPL query won't return any results and won't raise errors either.

SELECT
     src_endpoint.ip,
     dst_endpoint.ip 
FROM
securitylake.amazon_security_lake_glue_db_us_east_1.amazon_security_lake_table_us_east_1_vpc_flow_2_0
WHERE time_dt BETWEEN CURRENT_TIMESTAMP - INTERVAL '1' DAY AND CURRENT_TIMESTAMP
LIMIT 10



source = securitylake.amazon_security_lake_glue_db_us_east_1.amazon_security_lake_table_us_east_1_vpc_flow_2_0
| where time_dt > '2024-07-31 00:00:00 ' and region = 'us-east-1'
| fields src_endpoint.ip
| head 10 

How can one reproduce the bug?
Steps to reproduce the behavior:

1. Go to Data sources -> securitylake -> query data -> open log explorer
2. Run the follow queries:

SELECT
     src_endpoint.ip,
     dst_endpoint.ip 
FROM
securitylake.amazon_security_lake_glue_db_us_east_1.amazon_security_lake_table_us_east_1_vpc_flow_2_0
WHERE time_dt BETWEEN CURRENT_TIMESTAMP - INTERVAL '1' DAY AND CURRENT_TIMESTAMP
LIMIT 10



source = securitylake.amazon_security_lake_glue_db_us_east_1.amazon_security_lake_table_us_east_1_vpc_flow_2_0
| where time_dt > '2024-07-31 00:00:00 ' and region = 'us-east-1'
| fields src_endpoint.ip
| head 10

4. See returned results

What is the expected behavior?
Both fields are returned properly without the top fields stripped.
