This change allows to insert records into `ENUM` columns using
`Appender` interface.
`ENUM` values are specified as `Strings`, usage example:
```java
stmt.execute("CREATE TYPE mood AS ENUM ('sad', 'ok', 'happy');");
stmt.execute("CREATE TABLE tab1(col1 mood)");
try (DuckDBAppender appender = conn.createAppender("tab1")) {
appender.beginRow().append("sad").endRow();
appender.beginRow().append("happy").endRow();
}
```
Additionally `append(byte[])` method now can be used to insert `VARCHAR`
records and `BLOB` columns can be used inside `LIST`s or `MAP`s.
Testing: new tests added for top-level and nested (inside `LIST`s)
`ENUM`s usage.
Fix: duckdb#416
