[altescy]

This PR add some features that makes use of manifest files:

Utilizing manifest files

• Add use_manifest option to QueueryClient
• If a manifest file is set to available (when use_manifest=True or enable_cast=True):
  • a manifest file is automatically downloaded before fetching data
  • a pandas.DataFrame returned by read(use_pandas=True) has column names according to the manifest
  • an iterator returned by __iter__(...) can be Sized object with the record count

map() method

In addition, map() method is added to Response and can be used as follows:

@dataclasses.dataclass
class Item:
    id: int
    title: str


client = QueueryClient(enable_cast=True)
response = client.run("select id, title from your_table")

for item in response.map(Item):
    assert isinstance(item, Item)
