Test Output Directory and .gitignore Configuration

[David-Morales-Norato]

Hello,

First, I would like to express my gratitude for this amazing library.

I am preparing a pull request for Odak and encountered an issue when running tests. A significant number of files are generated in the main folder, which clutters the directory.

Proposed Solution:

1. Test Output Directory: Implement a standard practice where each test saves its results in a designated subfolder within the test directory.
2. Ignore Configuration: Ensure that this subfolder is included in the .gitignore file to prevent undesired files from being included in commits.

Additional Information:

For reference, I have attached the git status output after cloning the main branch and running pytest.

Thank you for considering this enhancement; it will improve the organization of the project. I believe I could refactor the tests, but it will take me some time, and first I want to make a pull request about something else.

Best regards,

David Morales-Norato

I have updated the unit tests accordingly. Now, the unit tests are all writing to the same directory with a slightly better naming convention. Moving on forward, the results will be stored at test_output directory. The changes will be reflected to the upcoming odak==0.2.6 and if you use the repository for installing, you should have the changes incorporated already.

I am closing this issue as the necessary commits are in the repository. Please do not hesitate to revive it if needed in the future.
