New Streams class

[gk-brown]

Kilo 5.3.4 introduces a new Streams class that defines a single toType() method:

public static <T> Function<Object, T> toType(Class<T> type) { ... }

This method is primarily intended to simplify result set processing code like the following:

var queryBuilder = QueryBuilder.select(Employee.class);

try (var statement = queryBuilder.prepare(getConnection());
    var results = queryBuilder.executeQuery(statement)) {
    return results.stream().map(toType(Employee.class)).toList();
}

It also serves as a convenient and more flexible alternative to the now-deprecated BeanAdapter#coerceList() method.

As with the methods in Collections and Optionals, toType() is meant to be statically imported for maximum readability.
