feat: Firebase now supports mass transfer of data

[slashexx]

Description:

This feature introduces the ability to transfer data from Firebase to MongoDB in bulk, with each document being inserted into a separate collection based on a unique identifier (e.g., _id). Previously, the data was inserted into a single collection. This change enhances flexibility by allowing data to be distributed across multiple collections, making it more modular and easier to manage.
Changes:

• Dynamic Collection Creation: Each document is now inserted into a collection named dynamically using its unique identifier or another field (e.g., _id).
• Bulk Data Insertion: The system now supports inserting multiple documents at once, each into its corresponding collection.
• Refactored MongoDB Insertion Logic: The SendData function has been refactored to iterate through the transformed data and insert each document into its respective collection.

Benefits:

Improves data organization by distributing documents into different collections.
Facilitates easier data retrieval and management based on document attributes.
Increases scalability by separating data logically across collections rather than using a single large collection.

Usage:

The change automatically assigns each document to its respective MongoDB collection based on its _id.
The collections are dynamically created and populated as new data is processed.
