[Issue-41] - Fix Batch Control Override and Update Company Identification to Alphanumeric

[martinsd94]

Issue: #41

Overview:

This PR resolves two key issues:

1. Batch Control Override Fix: Corrects the batch control override logic.
2. Company Identification Update: Updates the companyIdentification field to support alphanumeric values, in line with modern NACHA practices that allow for greater flexibility.

Details:

• The NACHA Company Identification field was originally designed to be numeric, often using the Employer Identification Number (EIN) prefixed with a "1". However, as ACH payments expanded and proprietary codes became more common, financial institutions started to support alphanumeric Company IDs. This change accommodates different identification schemes, making it easier for various types of originators to comply.

Changes:

• Batch Control Fix: Fix batch control override logic.
• Company ID Update: Adjusted the type for companyIdentification field to allow alphanumeric characters, reflecting current standards.

Please review and merge if appropriate! :)
