Added a helper function for bc related warp functions

[hsalehipour]

Added a helper function for BCs to avoid repeated definition of identical warp functions.

Contributing Guidelines

• I have read and understood the CONTRIBUTING.md guidelines

Description

We cannot inherit methods in Warp. As a workaround, rather than repeating snippets to represent identical Warp functionalities (which is what is done currently in the code), this PR creates a helper function that keeps those methods. These methods are imported as needed inside construct_warp.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update

How Has This Been Tested?

• All pytest tests pass

Linting and Code Formatting

Make sure the code follows the project's linting and formatting standards. This project uses Ruff for linting.

Please add the helpers to the init and import them from xlb.helper similar to the other helper functions.

Please add the helpers to the init and import them from xlb.helper similar to the other helper functions.

It is not possible because the DefaultConfig is not set before xlb.init is called!
