Collection of DTOs as input parameters

Hi Team,

The library supports var args to pass multiple objects:
```
var account1 = new Account(1, "John");
var account2 = new Account(2, "Mary");
client.forSql("INSERT INTO accounts(accountId, name) VALUES(:accountId, :name)")
.withParamSets(account1, account2)
.execute();
```

If we need to pass Collection we have to call toArray():
```
List accounts = List.of(new Account(1, "John"), new Account(2, "Mary")....);
client.forSql("INSERT INTO accounts(accountId, name) VALUES(:accountId, :name)")
.withParamSets(accounts.toArray())
.execute();
```

Batch saving quite often is used with a list of objects and it would help to avoid extra call toArray().

Could you please add overloaded withParamSets method or a new method to pass java.util.Collection, for instance:
```
List accounts = List.of(new Account(1, "John"), new Account(2, "Mary")....);
client.forSql("INSERT INTO accounts(accountId, name) VALUES(:accountId, :name)")
.withParamCollection(accounts)
.execute();
```

Thank you.

まず withParamSets エントリポイントと、既存の varargs 処理を見つけます。呼び出し元とテストを確認し、現在の varargs の動作を維持したまま java.util.Collection 入力をサポートします。コレクションをバッチ実行用に直接渡せるようになれば完了です。
