Main feature: - Added functionality to randomly generate a maze before the solver solves it. Fixes: - Add a public method in the Cell class called wall_exists() that returns true if a given cell wall exists (false otherwise). Refactors: - Added an enum type called CellWallLabel for labelling the four cell walls. - Added a draw() function in the CellWall class to reduce repeated code. - Move the custom exceptions to errors.py Tests: - Add tests for the custom exceptions. CI: - Added a workflow for Forgejo Actions.
