feat: Add example test files to the pip installable module
Current behaviour:
Right now the example input pdb and FASTA formatted files are not part of the pip installable module. So if you pip install the module and run the following command from the README, picnic would throw an error that it cannot find the files under the notebook folder. So one would have to download these manually from the GitLab repo.
picnic False 'notebooks/test_files/O95613/' 'O95613' False --path_fasta_file 'notebooks/test_files/O95613/O95613.fasta.txt'
Expected behaviour:
Simple add these files to the package, cause they are not that big in size.
