feat: generate expr by pk type when delete entities by ids

[yuyicai]

The id on query and search result always is string type, even if the pk field type is int64.
So, we should generate the expr by the type of pk field when delete data by ids.

example:
index.ts

import { MilvusClient, InsertReq, DataType } from '@zilliz/milvus2-sdk-node';

const COLLECTION_NAME = 'data_query_example';

(async () => {
  // build client
  const milvusClient = new MilvusClient({
    address: 'localhost:19530',
    username: 'username',
    password: 'Aa12345!!',
  });

  console.log('Node client is initialized.');
  // create collection
  const create = await milvusClient.createCollection({
    collection_name: COLLECTION_NAME,
    fields: [
      {
        name: 'id',
        description: 'ID field',
        data_type: DataType.Int64,
        is_primary_key: true,
      },
      {
        name: 'vector',
        description: 'Vector field',
        data_type: DataType.FloatVector,
        dim: 8,
      },
      { name: 'height', description: 'int64 field', data_type: DataType.Int64 },
      {
        name: 'name',
        description: 'VarChar field',
        data_type: DataType.VarChar,
        max_length: 128,
      },
    ],
  });
  console.log('Create collection is finished.', create);

  // build example data
  const vectorsData = [
    {
      id: 1,
      vector: [
        0.11878310581111173, 0.9694947902934701, 0.16443679307243175,

  const params: InsertReq = {

  // insert data into collection
  await milvusClient.insert(params);
  console.log('Data is inserted.');

  // create index
  const createIndex = await milvusClient.createIndex({
    collection_name: COLLECTION_NAME,
    field_name: 'vector',
    metric_type: 'L2',
  });

  console.log('Index is created', createIndex);

  // need load collection before search
  const load = await milvusClient.loadCollectionSync({
    collection_name: COLLECTION_NAME,
  });
  console.log('Collection is loaded.', load);

  // do the query
  console.time('Query time');
  const query = await milvusClient.query({
    collection_name: COLLECTION_NAME,
    filter: 'height > 31400',
    output_fields: ['id', 'height'],
    limit: 100,
  });
  console.timeEnd('Query time');
  console.log('query result', query);

  // get ids for query result
  // and type of id, the id always is string type
  const ids = query.data.map((item: any) => {
    console.log(item, "id type:", typeof item.id);
    return item.id;
  });
  
  // delete data by ids that query result returned
  const deleteRet = await milvusClient.delete({
    collection_name: COLLECTION_NAME,
    ids,
  })
  console.log('delete result', deleteRet);

  // drop collection
  await milvusClient.dropCollection({
    collection_name: COLLECTION_NAME,
  });
})();
