Environment details

• Programming language: Python
• OS: Mac OS 13.2.1
• Language runtime version: 3.9.16
• Package version: sqlalchemy 2.0.15, sqlalchemy-spanner 1.6.2

Steps to reproduce

Following the directions in the README, I wrote the following:

from sqlalchemy import create_engine, Table
from sqlalchemy.schema import MetaData

engine = create_engine(
    f"spanner+spanner:///projects/{project}/instances/{instance}/databases/{database}"
)
        metadata = MetaData(bind=engine)

and got the error:

    metadata = MetaData(bind=engine)
TypeError: __init__() got an unexpected keyword argument 'bind'

It seems the README might be out of date - what is the new way of connecting to tables? I was hoping to insert data.
