Implement Patch Apply

[sweep-ai]

Description

This PR implements the missing functionality to apply a patch in the csharpdiff repository. The Apply method in the PatchApply class has been implemented to parse a unified diff string and apply the changes to a given source string.

Summary of Changes

• Implemented the Apply method in the PatchApply class to parse a unified diff string and apply the changes to a source string.
• Parsed the unified diff string into a list of changes, each specifying an operation, position, and text.
• Applied the changes to the source string in the order they appear in the diff.
• Returned the resulting string after all changes have been applied.

Fixes #3.

I'm getting the same errors 3 times in a row, so I will stop working on fixing this PR.

sweep: you are missing } in PatchApply.cs and afterwards your unit tests fail with System.IndexOutOfRangeException : Index was outside the bounds of the array.

Hi @ThomasHambach,

I decided to make the following changes:

File Path	Proposed Changes
CSharpDiff/Patches/PatchApply.cs	Modify CSharpDiff/Patches/PatchApply.cs with contents: • Add a closing curly brace (}) at the end of the PatchApply class in the PatchApply.cs file.
CSharpDiff.Tests/PatchTests.cs	Modify CSharpDiff.Tests/PatchTests.cs with contents: • Investigate the IndexOutOfRangeException in the unit tests and fix the issue causing it.
