New streamOf() methods

[gk-brown]

Kilo 5.3.5 adds two new methods to the Streams class:

public static <T> Stream<T> streamOf(Iterable<T> iterable) { ... }
public static <T> Stream<T> streamOf(Collection<T> collection) { ... }

The first offers a less verbose alternative to the java.util.stream.StreamSupport#stream() method:

var iterable = (Iterable<Integer>)listOf(1, 2, 3);

var a = StreamSupport.stream(iterable.spliterator(), false).findFirst().orElseThrow(); // 1
var b = streamOf(iterable).findFirst().orElseThrow(); // 1

It also provides an alternative to the now-deprecated ResultSetAdapter#stream() method:

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

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

The second version is provided for consistency and simply delegates to java.util.Collection#stream().

The Streams class is now deprecated. New code should use Iterables instead.
