This change improves support for integer types in `ResultSet`. It allows to fetch more narrow types (like `SMALLINT`) using `getObject()` calls with more wide type parameter (like `BIGINT`). It also adds support for fethching `HUGEINT` values as instances of a `BigInteger` class and adds new methods to `Connection` to be able to insert 128-bit `HUGEINT` values passing them as a pair of `long`'s or as a `BigInteger`. Additonally it corrects JDBC types mapping for integer types and changes the fallback JDBC type from `JAVA_OBJECT` to `OTHER`. Testing: new tests are added to cover integer values fetching from `ResultSet`; existing `ResultSet` tests moved to separate files. Fixes: duckdb#204
