This is the documentation for updatemysql1A.py.
This file contains a set of functions that:
1. Create tables in the MySQL database if they do not yet exist.
2. After establishing a connection to the MySQL server,
tables for farside, XT-cut, composite map, SO-PHI, and synoptic map can be created
and populated with the following information: tag, filename, date_range, latest_date, caption, file_creation_time, and filepath.

Summary:
Connect to a MySQL server using the provided configuration and return the connection object.
Description:
This function establishes a connection to a MySQL server using the parameters specified in the
~/.my.cnf configuration file and connects to the 'Farside' database. If the connection is
successful, it returns the connection object. If the connection fails, a RuntimeError is raised.
Parameters: None
Returns:
pymysql.connections.Connection: A connection object to the MySQL server.
Raises:
RuntimeError: If the connection to the MySQL server is not open.
Example:
>>> connection = connect_to_mysql()
>>> # Perform database operations using the 'connection' object.
