PR Summary: Initial Base Code for SplitFile

This PR establishes the initial foundational load for the splitfile utility. It introduces a lightweight, efficient C# console application designed to deconstruct large delimited text files into smaller, manageable segments.

Core Functionality

Stream-Based Splitting: Implements a StreamReader/StreamWriter pattern to process large files line-by-line, ensuring low memory overhead regardless of the source file size.
Header Preservation: Includes logic to detect and replicate the header row across all generated sub-files, maintaining data integrity for downstream processing.
Intelligent File Sizing: Automatically calculates segment sizes (defaulting to 10% of the original file) or accepts custom maxSize constraints.
Flexible Formatting: Supports configurable output file naming conventions via standard C# string formatting (e.g., gmdnTerms-{0:000}.txt).

Project Components

File	Description
Program.cs	Contains the core `Split` logic, including encoding detection and file stream management.
splitfile.csproj	Configured for .NET 6.0 with Implicit Usings and Nullable reference types enabled.
splitfile.sln	Visual Studio 2022 solution file for local development.

Usage Notes

The current entry point is configured to process the AccessGUDID delimited release files. To target different files, update the path, input, and format variables within Main.

Note for Reviewers: This is a focused initial commit (3 files) that provides a functional baseline for file manipulation. The implementation includes a finally block to ensure all file handles are properly disposed of, even in the event of an I/O failure.
