[0] index organised tables are in fact stored as multiple "overflow" tables, and when querying all_tables, we only see the overflow tables, but they refer to the index organised table through their IOT_NAME, which is the table we need to query.
also fixed an issue where if we could see a table but didn't have access to it, we would panic
Tested manually by discovering and capturing an index organised table, and on a database which has tables which the user cannot access.
Fixed the tests by isolating the tables used for testing in a specific schema so that the tests are more deterministic.
Fixed some issues with capturing empty tables and identifier quoting.
Refactored fetching of MAX(ROWID) into a PL/SQL so we don't have round-trips for each table
Oracle's numeric types have precision 38 by default. Updated the discovery and encoding logics to use string for numbers with precision higher than 18
