The key and endpoint are set, but the corresponding address is not modified when accessing, and there is no place to set s3_url_style

```sql
D load httpfs;
D set s3_use_ssl='false';
D set s3_url_style='path';
D set s3_endpoint='minio:9000';
D set s3_access_key_id ='xxxxxxxxxxxxxxxxxx';
D set s3_secret_access_key ='xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
D select * from read_csv('s3://jyt/test.csv');

It can be accessed normally in duckdb

Correct, s3_url_style is not currently settable.

As discussed a bit in #197, we might want to move towards a more flexible way of supporting all the various options. For instance it would also be nice to support the scope option… and there's many others.

I guess this will be fixed by #151, once we implement it.
