Add Support for Column Name Mapping in Options

[david-ort]

Summary:

Add support for column name mapping in the options object to allow developers customize the names of the columns used to store session data in the database.

Description:

Currently, the package uses a set of predefined column names for storing session data (e.g., sid, session, expires). To enhance flexibility and integration with existing databases, it would be beneficial to allow developers to map these column names to custom names of their choosing.

Motivation:

• Database Integration: Many applications need to integrate with pre-existing databases that may have different naming conventions or existing columns for session data.
• Flexibility: Customizable column names can help avoid conflicts with other tables or columns in the database.
• Consistency: Developers can maintain consistency in their database schema by aligning session table column names with their project's naming conventions.

I know it might seem like a small thing, but I think it would be useful.

@david-ort Not a small thing at all! I think this is a great idea. I'll try to get to this this week.

This is still a WIP. I started working on it, but have been swamped with work/home life. Will continue with it when time permits. Thank you in advance for your patience :D
